EVATHENE® UE629
乙烯醋酸乙烯共聚物
USI Corporation
产品说明:
EVATHENE UE629 is the ethylene-vinyl acetate copolymer(EVA), possessing many excellent characteristics including flexibility, elasticity, transparency, non-toxicity, good resistance to environmental stress cracking, low temperature flexibility, easy processability and etc. For these characteristics, The EVATHENE UE629 can be used to develop the new applications and replace the flexible PVC, rubbers and other elastomers. One of the applications is the incorporation of foaming agents, crosslinking agents and inorganic fillers with EVATHENE UE629 for injection and compression molding of foamed mid-sole material for shoes.
EVATHENE UE629 is extruded to sheet such as casting and co-extrusion for special packaging of hospital and medical materials, food packaging and other packaging.

乙烯-醋酸乙烯共聚物简称EVA,一般醋酸乙烯(VA)含量在5%~40%。与聚乙烯相比,EVA[1]由于在分子链中引入了醋酸乙烯单体,从而降低了高结晶度,提高了柔韧性、抗冲击性、填料相溶性和热密封性能,被广泛应用于发泡鞋料、功能性棚膜、包装膜、热熔胶、电线电缆及玩具等领域。
