Dè an diofar eadar foam EVA, EPE foam, agus foam sponge

1. Foam eva (Bidh Vinysne Vinyste acetate Erylne acetate)

Feartan:

• Fine and uniform cell structure (uachdar rèidh)
• High elasticity and toughness
• Good water resistance and durability
• Can be bàs-ghearradh, cruth-teasachaidh, laminated, no clò-bhuailte easily
• Raon dùmhlachd: 30–300 kg/m³
• Ri fhaighinn ann an various colors and hardness levels

Cleachdaidhean àbhaisteach:

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

Nithean matha: Crìochnachadh rèidh, seasmhach, gnàthaichte, neo-phuinnseanta
Cons: Slightly more expensive than EPE

2. EPE Foam (Polyethylene leudaichte)

Feartan:

• Lightweight with larger air bubbles / open cells
• Soft and flexible, excellent sùghadh clisgeadh
• Water and chemical resistant
• Raon dùmhlachd: 15–50 kg/m³

Cleachdaidhean àbhaisteach:

• Pacadh (electronics, glass, àirneis)
• Edge protectors, foam tubes, insulation

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

3. Foam sponge (Polyurethane or PU Foam)

Feartan:

• Structar cealla fosgailte (soft and breathable)
• Very compressible and comfortable
• Absorbs water easily
• Raon dùmhlachd: 10–60 kg/m³

Cleachdaidhean àbhaisteach:

• Seat cushions, ionsadh fuaim, cosmetic sponges
• Cleaning products, gaskets, padding

Nithean matha: Very soft, cofhurtail, low cost
Cons: Absorbs water, poor durability outdoors, not suitable for heavy loads
