What is the difference between EVA foam, I-epe foam, and sponge foam

1. I-Eva foam (I-Ethylene Vinyl Acetate)

Iimbonakalo:

• Fine and uniform cell structure (indawo egudileyo)
• High elasticity and toughness
• Good water resistance and durability
• Can be Ukusika, Ubushushu, laminated, okanye iprintwe easily
• Density range: 30–300 kg/m³
• Ifumaneka ngaphakathi various colors and hardness levels

Typical Uses:

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

Pros: Smooth finish, hlalani, ngokuqinisekileyo, enganetyhefu
Cons: Slightly more expensive than EPE

2. EPE Foam (Expanded Polyethylene)

Iimbonakalo:

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

Typical Uses:

• Ukupakisha (i-elektroniki, glass, ifenitshala)
• Edge protectors, foam tubes, ukufakwa

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

3. I-Sponge Foam (Polyurethane or PU Foam)

Iimbonakalo:

• Ulwakhiwo lweseli evulekileyo (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
