Braskem EVA HM 2528
乙烯醋酸乙烯共聚物
Braskem
產(chǎn)品說明:
Evateno ® HM 2528 is a copolymer of Ethylene-Vinyl Acetate (EVA) with high vinyl-acetate content, low molecular weight, and good compatibility with other thermoplastic and elastomeric resins. It can be use in blends with other polyethylenes to improve environmental stress cracking resistance (ESCR), impact resistance, and brittleness at low temperatures. It contains antioxidant additive.
Application:
Hot-melt adhesives, coatings, expanded plaques, and injection and extrusion molded parts where flexibility, resilience and environmental stress crack resistance (ESCR) are required. Hot-melt adhesives bulation presents excellent compatibility with wax, paraffins and tackfiers, improving flexibility and adherence.
