EVATHENE® UE631

Ethylene Vinyl Acetate Copolymer

USI Corporation

产品说明：

UE632 is a high VA content ethylene-vinyl acetate copolymer(EVA) with excellent low temperature impact strength, environmental stress crack resistance, flexibility, elasticity, transparency, and easy processability. It could be developed for many new applications and substitute for flexible PVC, rubbers, and other elastomers. One of major application of UE632 is incorporated with blowing agent and cross-linking agent for compression molding or injection molding of foamed shoe sole. Besides, UE632 could be processed by profile extrusion, injection molding, and blown-extrusion while incorporated with additives.
