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

1. EVA-skuim (Etileen viniel asetaat)

Kenmerke:

• Fine and uniform cell structure (gladde oppervlak)
• High elasticity and toughness
• Good water resistance and durability
• Can be gesny, hitte gevorm, laminated, of gedruk easily
• Density range: 30–300 kg/m³
• Beskikbaar in various colors and hardness levels

Typical Uses:

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

Pros: Smooth finish, duursaam, aanpasbaar, nie-toksies
Cons: Slightly more expensive than EPE

2. EPE-skuim (Expanded Polyethylene)

Kenmerke:

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

Typical Uses:

• Verpakking (elektronika, glass, meubels)
• Edge protectors, foam tubes, isolasie

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

3. Spons skuim (Polyurethane or PU Foam)

Kenmerke:

• Oopselstruktuur (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, opvulling

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