Braskem EVA VA2019A
乙烯醋酸乙烯共聚物
Braskem
產(chǎn)品說(shuō)明:
VA2019A is a copolymer of Ethylene-Vinyl Acetate (EVA) with medium vinyl-acetate content. VA2019A is an easy processing product highly compatible with other thermoplastic and elastomeric resins, and mineral loads. Its elasticity is higher than the LDPE of the same MI. It presents excellent environmental stress crack resistance (ESCR) and low temperature brittleness. Compounds produced with VA2019A will be light, resistant to debation and with color retention.
Application:
Crossbed and/or expanded parts for several applications including compounds for footwear (sole, insoles, etc), toys and freebie industry, produced by injection molding. Polymeric blends.
