What is the difference between EVA foam, cúr EPE, and sponge foam

1. Eva Foam (Aicéatáit vinile eitiléine)

Bheith:

• Fine and uniform cell structure (smooth surface)
• High elasticity and toughness
• Good water resistance and durability
• Can be bás-ghearrtha, teas-déanta, laminated, nó clóite easily
• Density range: 30–300 kg/m³
• Ar fáil i various colors and hardness levels

Typical Uses:

• Sports mats, yoga blocks, swimming belts
• Packaging inserts (high-end electronics, uirlisí)
• Shoe soles, kneeling pads, toys

Pros: Smooth finish, marthanach, customizable, neamh-tocsaineach
Cons: Slightly more expensive than EPE

2. EPE Foam (Expanded Polyethylene)

Bheith:

• Lightweight with larger air bubbles / open cells
• Soft and flexible, excellent ionsú turraing
• Water and chemical resistant
• Density range: 15–50 kg/m³

Typical Uses:

• Pacáistiú (leictreonaic, glass, furniture)
• Edge protectors, foam tubes, insliú

Pros: Low cost, good cushioning, ath-inúsáidte
Cons: Rougher surface, less firm than EVA, not suitable for precision cutting

3. Foam Spúinse (Polyurethane or PU Foam)

Bheith:

• Open-cell structure (soft and breathable)
• Very compressible and comfortable
• Absorbs water easily
• Density range: 10–60 kg/m³

Typical Uses:

• Seat cushions, sound absorption, cosmetic sponges
• Cleaning products, gaskets, padding

Pros: Very soft, comfortable, low cost
Cons: Absorbs water, poor durability outdoors, not suitable for heavy loads
