Product description
7350M is an ethylene/vinylene acetate copolymer. The trade name is Taisox. 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. 7350M is a general-purpose for X-linked foam shoes, mid-sole, gaskets. It provides good chemical resistance, excellent elasticity, and high flexible properties.
