Ethylene vinyl acetate or EVA is a copolymer of ethylene and vinyl acetate which an extremely elastic and tough thermoplastic of excellent clarity and gloss and with little odor.
EVA has many attractive properties including
1. Low cost
2. Excellent adhesion to many polar and nonporous substrates
3. Good flex-crack and puncture resistance
4. Good hot-tack and heat-sealing.
Taisox 7350M is an ethylene/vinylene acetate copolymer. This product is manufactured by the high-pressure process. By incorporating vinyl acetate (VA) into the ethylene chain, the high-pressure process produces co-polymerization to EVA. Taisox 7350M is a general-purpose for X-linked foam shoes, mid-sole, gaskets. It provides good chemical resistance, excellent elasticity, and high flexible properties.
