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

1. Eva ko'pik (Etilen vinil asetat)

Xususiyatlari:

• Fine and uniform cell structure (silliq sirt)
• High elasticity and toughness
• Good water resistance and durability
• Can be die-cut, heat-formed, laminated, yoki bosma easily
• Density range: 30–300 kg/m³
• Mavjud various colors and hardness levels

Typical Uses:

• Sports mats, yoga blocks, swimming belts
• Packaging inserts (high-end electronics, Asboblar)
• Shoe soles, kneeling pads, o'yinchoqlar

Pros: Smooth finish, bardoshli, odatlangan, zaharli bo'lmagan
Cons: Slightly more expensive than EPE

2. EPE ko'pik (Kengaytirilgan polietilen)

Xususiyatlari:

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

Typical Uses:

• Qadoqlash (elektron, glass, mebel)
• Edge protectors, foam tubes, izolyatsiya

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

3. Shimgich ko'pik (Polyurethane or PU Foam)

Xususiyatlari:

• Ochiq uyali tuzilma (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, to'ldirish

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