EVATHENE® UE629

Ethylene Vinyl Acetate Copolymer

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.
