Ethylene-vinyl acetate (EVA)
Ethylene-vinyl acetate (EVA), also known as poly (ethylene-vinyl acetate) (PEVA), is the copolymer of ethylene and vinyl acetate. The weight percent vinyl acetate usually varies from 10 to 40%, with the remainder being ethylene. EVA is an elastomeric polymer that produces materials which are “rubber-like” in softness and flexibility. The material has good clarity and gloss, low-temperature toughness, stress-crack resistance, hot-melt adhesive waterproof properties, and resistance to UV radiation. EVA has a distinctive vinegar-like odor and is competitive with rubber and vinyl polymer products in many electrical applications. EVA is a commonly used material for sock liners, midsoles, outsoles and even entire shoes.
- Highly water and corrosion resistant
- Insulation towards cold temperature
- Anti-vibrant (good tensile strength & shock cushioning with high toughness)
- Offers ease of processing (cutting, gluing, pressing and laminating
- Closed foam sound insulation quality
