用途:一般醋酸乙烯含量在 5% 以下的 EVA 主要制成薄膜、电线电缆、LDPE 改性剂和胶粘剂等;醋酸乙烯含量 5%-10% 的 EVA 用于弹性薄膜;20%-28% 的 EVA 主要用于热熔胶和涂层制品;5%-45% 的 EVA 主要制成薄膜(含农膜)和片材、注塑和模塑制品、发泡制品及热熔胶等。
EVA can be processed by many different methods, such as injection molding, extrusion, blow molding, calendering and foaming. It is mainly used to produce packaging materials, agricultural film, injection-molded products, cable materials, plastic foam, masterbatch carriers, blend toughening materials and damping/sound-insulating materials. It is also used to make hot-melt adhesives, carpet backing, wax-based coatings and shoe soles. Through hollow (blow) molding, EVA can be made into flexible tubing such as expandable hose and micro-irrigation pipe.
EVA is packed in kraft-paper bags, 25 kg net per bag. The resin should be stored in a ventilated, dry warehouse away from fire and direct sunlight and should not be stacked outdoors. During transport the material must not be exposed to strong sunlight or rain, and must not be transported together with sand, soil, scrap metal, coal or glass.
