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.
It is a polymer that approaches elastomeric ("rubber-like") materials in softness and flexibility. This is distinct from a thermoplastic, in that the material is cross-linking, ergo difficult to recycle. 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 odour and is competitive with rubber and vinyl products in many electrical applications.
EVA/PEVA can be typically used in Suckers, Gum shields, Barrel Bungs, Ice Cube Trays, Carrier bag handles, and Flexible tubing.
