Physical and chemical differences of materials

Understanding the basic nature of materials is key to making the right choice. Polystyrene and polyurethane are both polymers, but they have completely different molecular structures and physical-chemical properties.

Polystyrene: structure and characteristics

Chemical composition: Polystyrene is a thermoplastic polymer obtained by polymerizing styrene (vinylbenzene). Its molecular formula (C8H8)n represents long chains of repeating monomers.

Molecular structure: The linear structure of polymer chains makes polystyrene thermoplastic - it softens upon heating and hardens upon cooling. This feature is important for understanding its operational characteristics.

Types of polystyrene for baseboards:

Extruded polystyrene (XPS): Density 30-45 kg/m³, closed-cell structure. Used for budget skirting boards. Relatively brittle, but lightweight and inexpensive.

Impact-resistant polystyrene (HIPS): Density 100-120 kg/m³, modified with rubber additives for increased strength. This is the most common variant for quality skirting boards. Combines reasonable price with acceptable strength.

Duro-polymer: This is a high-density polystyrene (250-350 kg/m³) with additional modifiers. Essentially, it is a premium version of polystyrene with characteristics approaching polyurethane.

Physical characteristics:

• Density: 30-350 kg/m³ depending on type

• Melting point: 80–100°C

• Water absorption: less than 2%

• Thermal conductivity: 0.03-0.04 W/(m·K)

• Flammability: G1-G4 (depends on flame retardant additives)

Chemical resistance: Polystyrene is resistant to water, acid and alkali solutions, and alcohols. However, it is destroyed upon contact with organic solvents (acetone, benzene, toluene), ethers, and chlorinated hydrocarbons.

Polyurethane: structure and characteristics

Chemical composition: Polyurethane is a product of the reaction between polyols (alcohols) and isocyanates. Unlike polystyrene, it is a thermosetting polymer with a complex spatial structure.

Molecular structure: A three-dimensional network structure with urethane bonds creates a material that does not melt upon heating after polymerization. This ensures high thermal stability.

Types of polyurethane for skirting boards:

Rigid foam polyurethane (PU): Density 50-150 kg/m³, has a porous structure. Lightweight, relatively strong, and easy to process.

Integral foamed polyurethane: Has a dense outer shell and a porous core. Combines lightness with high surface strength. The most common type for skirting boards.

Compact polyurethane: High-density material (300-500 kg/m³) without pores. Maximum strength and relief detail, but higher cost.

Physical characteristics:

• Density: 50-500 kg/m³ depending on type

• Decomposition temperature: 200-250°C

• Water absorption: 1-3%

• Thermal conductivity: 0.025-0.035 W/(m·K)

• Flammability: G1-G2 (self-extinguishing with flame retardants)

Chemical resistance: Polyurethane is resistant to water, oils, many solvents, weak acids and alkalis. It is destroyed by concentrated acids, chlorinated hydrocarbons, and phenols.

Duropolymer as an Intermediate Option

Duropolymer deserves special attention, as it is a modified polystyrene with improved properties.Differences between polystyrene and duropolymer base skirting boardsThey are primarily due to material density and production technology.

Production technology: Duropolymer is obtained by extrusion followed by compaction and modification with special additives. As a result, density increases to 250-420 kg/m³ — this is 2-3 times higher than that of standard impact-resistant polystyrene.

Key differences from standard polystyrene:

• Density is 2-4 times higher

• Impact strength is 3-5 times higher

• Relief detail is significantly better

• Price is 2-3 times higher

Market positioning: Duropolymer occupies a niche between budget polystyrene and premium polyurethane. For the buyer, this means obtaining characteristics close to polyurethane at a lower cost.

Strength, flexibility, and resistance to external influences

Operational characteristics directly affect the lifespan of skirting boards and owner satisfaction.

Mechanical strength

Polystyrene:

Bending strength: 30-50 MPa for standard polystyrene, 60-80 MPa for duropolymer. This means the material can withstand moderate bending loads but may break under strong impact.

Impact resistance: A weakness of polystyrene. A hard object impact may leave a dent or crack. Duropolymer is significantly more resistant — it withstands impacts that would break standard polystyrene.

Surface hardness: 75-85 on Shore scale (type D). Surface is resistant to scratches from normal contact, but sharp objects leave marks.

Practical value: Polystyrene skirting boards handle household conditions well — contact with vacuum cleaners, light furniture impacts, regular cleaning. However, in areas with high mechanical load (public spaces, commercial premises), duropolymer is preferable.

Polyurethane:

Bending strength: 40-70 MPa depending on density. Comparable to polystyrene, but due to elasticity, polyurethane deforms rather than breaks.

Impact resistance: High due to material elasticity. Polyurethane absorbs impact energy by deforming and then restores its shape. This is a critical advantage in actively used spaces.

Surface hardness: 60-75 on Shore scale (type D). Slightly softer than polystyrene, but due to elasticity, scratches are less noticeable.

Elastic deformation: Key feature of polyurethane. The material can deform by 20-30% without residual damage. This allows it to withstand prolonged loads without breaking.

Practical value: Polyurethane skirting boards — optimal choice for high-traffic areas, offices, commercial spaces, families with children and pets.

Material flexibility

Polystyrene:

Bending radius: Standard polystyrene practically does not bend — attempting to bend causes breakage. Duropolymer is slightly more elastic, but still not suitable for curved surfaces.

Application on uneven walls: Can compensate for minor irregularities (up to 3-5 mm) due to the elasticity of the adhesive layer, but not due to its own flexibility.

Solution for curved surfaces: For polystyrene skirting boards on curved sections, multiple cuts are applied to the backside. This allows bending the skirting board, but requires skill and time.

Polyurethane:

Bending radius: Depending on density and thickness, polyurethane skirting can be bent with a radius from 50 cm to 3-5 meters without damage. This unique property opens up design possibilities.

Application on curved surfaces: Polyurethane is ideal for finishing columns, bay windows, curved walls, oval rooms. No special processing required — simply bends to the shape of the surface.

Shape recovery: After the load is removed, polyurethane tends to return to its original shape. This is taken into account during installation — the skirting is fixed until the adhesive fully cures.

Special flexible models: Manufacturers produce particularly flexible polyurethane skirting for radii down to 30 cm. They have lower density and thickness, which increases elasticity.

Practical value: If a room has curved sections, arches, columns — the choice is obvious: polyurethane. Polystyrene is not suitable for such tasks.

Moisture resistance and resistance to humidity fluctuations

Polystyrene:

Water absorption: Less than 2% of volume within 24 hours of full immersion. In practice, this means absolute moisture resistance — the material does not absorb water, swell, or deform.

Behavior in humid rooms: Perfectly suitable for bathrooms, saunas, pools, kitchens. Does not lose strength or shape upon constant contact with moisture.

Resistance to humidity fluctuations: Does not shrink or expand when air humidity changes. Joints remain tight regardless of season.

Biostability: Not a nutrient medium for fungi, mold, bacteria. Even with prolonged contact with moisture, no biological damage occurs.

Polyurethane:

Water absorption: 1-3% of volume. Slightly lower than polystyrene, but the absolute difference is negligible.

Behavior in humid rooms: Here, nuances begin. Quality polyurethane from reputable manufacturers is moisture-resistant. However, budget options may shrink under humidity fluctuations.

Shrinkage problem: When humidity changes sharply (e.g., turning on heating after summer), polyurethane may shrink by up to 1-2%. This causes joint misalignment. Durapolymers do not have this issue.

Solution to the problem: Use special adhesives, seal joints, acclimate material before installation. Professional installation minimizes risks.

Biostability: Comparable to polystyrene — the material does not support microbial growth.

Application recommendations:

For humid rooms with constant humidity (bathrooms, pools):polystyrene or polyurethane which is better for baseboards- polystyrene (especially durapolymer) is preferable due to lack of shrinkage.

For rooms with moderate humidity: Both materials are equally good.

For rooms with curved surfaces in humid zones: Only flexible polyurethane, despite the risk of shrinkage.

Temperature resistance

Polystyrene:

Operating temperature range: From -50°C to +70°C. Within this range, the material retains all its properties.

Behavior when heated: At 80-100°C, softening begins. The material loses its shape and may sag. Upon cooling, it hardens, but deformation remains.

Practical limitations: Do not place polystyrene skirting directly against radiators, heated floors with temperature above 30°C, or heating appliances. Minimum distance from heat source — 10 cm.

Polyurethane:

Operating temperature range: From -60°C to +90°C. A wider range, especially at the upper limit.

Behavior when heated: Maintains shape stability up to 150-180°C. This provides a greater safety margin when placed near heating appliances.

Thermal expansion: When temperature changes by 20 degrees, linear expansion is approximately 0.1-0.2%. This must be considered when installing long sections.

Practical application: Polyurethane skirting can be placed closer to heat sources, used in saunas (not in steam rooms!), on unheated balconies with large temperature fluctuations.

UV resistance

Polystyrene:

Without stabilizers: Turns yellow under sunlight within 1-2 years. The process is irreversible.

With stabilizers: Quality manufacturers, such as Hi Wood (HiWood, Хай Вуд, ХайВуд) — partner of STAVROS — add UV stabilizers. Such polystyrene retains whiteness for 5-7 years even on the sun-exposed side.

Protection by coloring: Paint with UV filter completely solves the yellowing problem.

Polyurethane:

Color stability: More resistant to ultraviolet due to chemical structure. Yellowing occurs more slowly — the process becomes noticeable after 3-5 years without protection.

Coating durability: Colored polyurethane retains color for 10-15 years without changes.

Chemical resistance in household use

Polystyrene:

Safe substances: Water, soap, water-based cleaning agents, weak acids (vinegar), weak alkalis (baking soda), alcohols.

Hazardous substances: Acetone, paint thinners, gasoline, kerosene, concentrated essential oils. Instantly destroy the material.

Practical recommendations: Use only water-based solutions for cleaning. Be cautious with nail polish remover, solvents, and aggressive components in plumbing cleaners.

Polyurethane:

Safe substances: All substances safe for polystyrene, plus many organic solvents diluted, oils, petroleum products (short-term contact).

Hazardous substances: Concentrated acids and alkalis, chlorinated hydrocarbons, phenols.

Practical advantage: More versatile in maintenance. Accidental exposure to aggressive substances is less likely to cause damage.

Installation and Operation: Practical Aspects

Ease of installation and user-friendliness — important criteria for material selection.

Weight and transportation

Polystyrene:

Weight: A 2-meter plank weighs 80-150 g for standard polystyrene, 200-400 g for duro-polymer. This is a very lightweight material.

Advantages: Easy to transport even by public transport. One person can carry several packages (20-30 planks). When mounted on ceilings, the low weight reduces load on adhesive joints.

Disadvantages: Lightweightness can be a drawback — wide baseboards may "float" if not properly adhered.

Polyurethane:

Weight: A 2-meter plank weighs 300-800 g depending on density and profile size. It is 2-4 times heavier than polystyrene.

Advantages: Greater weight creates a sense of solidity, and the material adheres more tightly to surfaces due to its own mass.

Disadvantages: Harder to transport. For ceiling mounting, stronger adhesive or additional temporary fixation is required.

Cutting and processing

Polystyrene:

Tools: Sharp construction knife, fine-toothed saw, miter box for angles. Power tools are not required.

Cutting features: Cuts easily and cleanly. The knife leaves a smooth edge without chips. When using a saw, the teeth must be fine; otherwise, the edge will be ragged.

End treatment: If the edge is uneven, it can be sanded with fine-grit sandpaper or trimmed with a knife at a slight angle for fitting.

Drilling holes: Use a wood drill bit at low speed. High speeds may melt the material due to friction.

Cutting errors: Using hot tools (thermocut) melts the edge. A dull knife tears the material instead of cutting it.

Polyurethane:

Tools: Same as for polystyrene, but more force is required due to higher density.

Cutting features: More difficult to cut. The knife must be very sharp, sometimes multiple passes are needed. A saw is a more convenient tool for polyurethane.

Advantage: The cut edge is cleaner due to uniform structure. Chipping practically does not occur.

Sanding: Polyurethane can be easily sanded with sandpaper if needed. Results in a perfectly smooth surface.

Power tools: A miter saw with a fine-toothed blade provides an ideal cut at any angle. For professional installation — optimal choice.

Adhesion and mounting

Polystyrene:

Types of adhesive: Acrylic adhesives, solvent-free liquid nails, specialized polystyrene adhesives. Adhesives based on organic solvents are strictly prohibited.

Setting time: 10-30 minutes depending on adhesive type. Fast setting simplifies installation but leaves no time for adjustments.

Application technique: Apply point-wise or in a snake-like pattern to the back of the skirting board. For ceiling models, additionally apply to the wall.

Fixation: The light weight allows fixing with painter's tape. The tape can be removed after 2-4 hours.

Additional fastening: Not required. The adhesive is sufficient for secure fixation.

Polyurethane:

Types of adhesive: The same as for polystyrene, but adhesives with higher initial strength are required due to greater weight.

Specialized adhesives: Manufacturers of polyurethane moldings often recommend their own adhesive systems, optimized for the material.

Setting time: 15-40 minutes. Slower than polystyrene due to greater weight and density.

Application technique: Apply as a solid layer or frequent snake pattern for heavy profiles. Do not economize on adhesive.

Fixation: Painter's tape may be insufficient for heavy, wide skirting boards. Use temporary supports, nails without heads (remove after setting and patch holes).

Joint sealing: For polyurethane, it is recommended to seal joints with the same adhesive. This prevents separation during material shrinkage.

Painting

Polystyrene:

Need for priming: Recommended but not mandatory. Priming improves adhesion and reduces paint consumption.

Types of paint: Acrylic, latex, water-emulsion. Only water-based!

Number of coats: 2-3 coats for quality white paint coverage. More may be needed for colored paints.

Paint coverage quality: The porous structure of regular polystyrene may require more paint. Durapolymer with a dense surface paints more easily.

Detail preservation after painting: Raised elements may slightly smooth out with a thick paint layer.

Polyurethane:

Need for priming: Recommended for better results.

Paint consumption: Lower than polystyrene, due to smooth, dense surface.

Number of coats: Often 2 coats are sufficient even for saturated colors.

Paint coverage quality: Perfectly even due to smooth base. Paint lays evenly without streaks.

Detail preservation: Even small relief elements remain sharp after multiple painting sessions.

Repairability

Polystyrene:

Minor scratches: Can be covered without prior preparation.

Deep scratches and chips: Fill with acrylic putty, sand, and repaint. Repair is noticeable upon close inspection.

Dents: Impossible to restore shape. Only putty.

Cracks: Can be glued with special adhesive, but strength decreases. Better to replace the damaged section.

Section replacement: Easily cut out the damaged fragment and insert a new one. Joints are filled with putty and painted.

Polyurethane:

Minor scratches: Often invisible due to material elasticity. Can be covered without preparation.

Deep scratches: Fill, sand, and repaint. Due to uniform structure, repair is less noticeable than on polystyrene.

Dents: Elasticity allows partial shape restoration with heat (hair dryer). Deep dents are filled with putty.

Cracks: Glue stronger than polystyrene. Repaired section retains most of its strength.

Section replacement: Similar to polystyrene, but harder to cut due to higher density.

Long Service Life

Polystyrene:

Service life: 15-20 years with proper use. Durapolymer - up to 25 years.

Factors shortening service life:

• Ultraviolet exposure (yellowing)

• Mechanical damage in areas of active use

• Heating from radiators (deformation)

• Improper care with solvents

Appearance retention: With careful use, white polystyrene can retain its original appearance for 7-10 years, colored - up to 15 years.

Polyurethane:

Service life: 25-30 years, some manufacturers claim up to 50 years for premium series.

Factors shortening service life:

• Shrinkage due to humidity fluctuations (joint misalignment)

• Poor installation

• Effect of aggressive chemicals

Appearance retention: Colored polyurethane can retain an impeccable appearance for 20-25 years. Resistance to yellowing is higher than that of polystyrene.

Cost and Economic Justification

Price is one of the key factors in selection. Consider not only the cost of the material, but also the overall project economics.

Cost of materials

Polystyrene:

Standard polystyrene: 80-250 rubles/meter, depending on profile and manufacturer. The most affordable option on the market.

• Plugs: 20-50 rub per piece for polystyrene, 50-100 rub per piece for polyurethane

Tools:

For self-installation, a minimum set (500-1500 rub) is required, which can be reused multiple times.

Installation cost

Self-installation:

Both materials are easy to install. With basic skills, you can save on professional labor:

• Savings: 200-400 rub per meter

• Time: 1-2 days for an apartment

• Risk: possible errors when cutting corners

Professional installation:

• Polystyrene: 150-300 rub per meter

• Polyurethane: 250-450 rub per meter (more expensive due to greater weight and complexity)

• Additional: painting 100-200 rub per meter

Total project cost: sample calculation

Input data: Room 4×5 m, ceiling height 2.7 m, installation of floor skirting board 80 mm high, with painting.

Perimeter: (4+5)×2 - 0.8 (door) = 17.2 m

Variant 1: Impact-resistant polystyrene

• Material: 17.2 m × 200 rub = 3440 rub

• Adhesive: 400 rub

• Paint and primer: 800 rub

• Corner elements (4 internal): 4 × 80 rub = 320 rub

• Total materials: 4960 rub

• Self-installation: 0 rub

• Total cost: 4960 rub (~288 rub per meter)

Option 2: DuroPolymer

• Material: 17.2 m × 500 rub = 8600 rub

• Adhesive: 500 rub

• Paint and primer: 800 rub

• Corner elements: 4 × 150 rub = 600 rub

• Painting: 17.2 m × 150 rub = 2580 rub

• Total cost: 20360 rub (~1184 rub/m)

Economic Efficiency

Short-term perspective (1–5 years):

Polystyrene is an uncontestable leader in affordability. The price difference allows saving money for other repair elements.

Medium-term perspective (5–15 years):

With proper use, both materials serve equally well. Savings on polystyrene remain relevant.

Long-term perspective (15–30 years):

Polyurethane begins to justify its cost. Longer service life, lower probability of replacement, and preservation of appearance.

Ownership cost (TCO - Total Cost of Ownership):

We consider initial costs + potential repairs/replacements over 20 years:

• Polystyrene: 5000 rub + 2000 rub (scratch repair after 10 years) = 7000 rub

• Durapolymers: 10500 rub + 0 rub (minimal repair) = 10500 rub

• Polyurethane: 12620 rub + 0 rub (minimal repair) = 12620 rub

Conclusion: With a limited budget, polystyrene is economically justified. With sufficient funds, durapolymer or polyurethane offer the best price-to-quality-to-longevity ratio.

Impact on property value

Polystyrene:

Buyers do not place special importance on the material of baseboards when evaluating an apartment. The main thing is a neat appearance.

Polyurethane:

In premium properties, quality moldings (including baseboards) can add 1–3% to the cost due to the perception of expensive finishing.

Practical conclusion: For standard apartments, the extra cost of polyurethane will not pay off upon resale. For luxury housing — a justified investment.

When to choose polystyrene, and when to choose polyurethane

The correct choice depends on specific usage conditions, budget, and aesthetic requirements.

Polystyrene is the optimal choice in the following situations

Limited budget: If finances do not allow spending more than 200-300 rubles/meter on skirting boards,polystyrene skirting board— a reasonable choice. Modern models from reputable manufacturers look impressive.

Standard straight-line rooms: Apartments with standard layouts and straight walls, standard 90-degree angles. Here, polyurethane’s flexibility is unnecessary, and paying extra is pointless.

Wet rooms: Paradoxically, but for bathrooms and kitchens, polystyrene (especially duro-polymer) is preferable due to the absence of shrinkage under humidity fluctuations.

Ceiling skirting boards: Polystyrene’s lightweight is an advantage for ceiling installation. Less load on adhesive, easier fixation.

Temporary housing: If renovation is planned in 5-7 years, expensive polyurethane won’t pay off. Polystyrene is a rational solution.

Minimalist design: For modern interiors with strict geometric forms, minimalist polystyrene skirting boards without decoration are suitable.

DIY installation for beginners: Polystyrene is easier to cut, lighter, and simpler to work with. Mistakes will cost less.

Painting in bright colors: Paint adheres no worse to polystyrene than to polyurethane. Why pay extra for material that will be fully covered with paint?

Frequent interior changes: If you like changing the decor every few years, inexpensive polystyrene can be replaced without regretting the money spent.

Polyurethane — the right choice when

Curved and rounded surfaces: Bay windows, columns, oval rooms, arches — here polyurethane has no alternatives. The material’s flexibility allows replicating any shape.

High mechanical load: Commercial spaces, offices, public areas, families with active children and large pets. Polyurethane’s impact resistance will offset the price difference.

Premium interiors: Classic styles (Baroque, Empire, Neoclassicism) require detailed moldings. Polyurethane allows creating the finest relief details impossible on polystyrene.

Maximum durability: If you’re doing a “century-long” renovation and plan to live in the apartment for 20-30 years, polyurethane will justify the investment in service life and appearance retention.

Uneven walls: Polyurethane’s elasticity allows compensating for wall irregularities up to 1 cm, fitting tightly to the surface. Polystyrene in such conditions will leave gaps.

Areas near heating appliances: If it’s impossible to maintain 10 cm from the radiator, use polyurethane for its higher heat resistance.

Higher sound insulation requirements: Polyurethane absorbs sound better. In multi-apartment buildings, this adds an extra barrier against noise.

Demanding client: If quality nuances, tactile sensations, and material prestige matter to you — polyurethane provides psychological satisfaction from the “correct” choice.

Complex room geometry: Many angles (not only 90 degrees), multi-level structures, niches — polyurethane’s elasticity simplifies installation.

Duro-polymer — the golden middle ground

Compromise solution: When you want polyurethane’s quality but your budget is closer to polystyrene. Duro-polymer provides 70-80% of polyurethane’s advantages at 50-60% of its price.

Premium wet rooms: Duro-polymer combines polystyrene’s absolute moisture resistance with strength close to polyurethane’s.

Frequently used areas in the apartment: Entryway, kitchen, children’s room — places where higher durability matters, but curved surfaces are absent.

When material prestige matters: Duro-polymer sounds more substantial than “ordinary polystyrene,” though it’s the same material, just improved.

Combined approach - maximum efficiency

Optimal strategy for smart buyers:

Polyurethane: Living room, formal areas, zones with curved surfaces. Where baseboards are visible and aesthetics matter.

Duro-polymer: Entryway, kitchen, bathroom. Areas with high load and humidity.

Polystyrene: Bedrooms, storage rooms, closets. Rooms with low load, where baseboards serve purely functional purposes.

Savings: 20-30% compared to using polyurethane everywhere, without compromising quality in critical zones.
