Jun 10, 2025
Differences Between PVC Foam Board and EPS Foam Board
| Criteria | PVC Foam Board | EPS Foam Board (Expanded Polystyrene) |
|---|---|---|
| Raw Material | Polyvinyl Chloride (PVC) + foaming agents | Polystyrene (PS) + foaming agents (e.g., pentane) |
| Density | 0.3–0.9 g/cm³ (adjustable) | 0.01–0.2 g/cm³ (extremely lightweight, floats on water) |
| Structure | Closed-cell or skinned surface, dense core | Open/closed-cell, fragile and crumbly |
| Strength | High compressive/flexural strength, load-bearing | Low strength, easily compressed/deformed |
| Weather Resistance | Acid/alkali-resistant, waterproof, UV-resistant, stable at -20°C to 70°C | Poor UV resistance, deforms at high temps (>80°C) |
| Eco-Friendliness | Recyclable, releases HCl when burned (requires flame retardants) | Non-biodegradable, releases toxic styrene when burned |
| Flame Resistance | Can achieve B1 fire rating with additives | Highly flammable, requires special treatment |
| Workability | Cut, engraved, thermoformed, laminated, printed | Limited to cutting and basic adhesion |
| Primary Uses | Signage, construction templates, furniture, vehicle interiors | Packaging, insulation, disposable tableware |
