EVA 台湾台塑 7470M 乙烯-醋酸乙烯酯共聚物 VA含量26% 发泡级
EVA是Ethylene和VA(Vinyl Acetate Monomer)的共聚物, 根据VA含量不同，
具有弹力和热黏合温度、内部结构、穿透力等也有所不同的特征。
不但用于太阳能板等高附加价值产品，而且也使用于鞋底、救生衣等多个领域
乙烯-醋酸乙烯酯共聚物（EVA）提供VA含量*高达33％的多样应用品别，以满足客户多样变化需求。 EVA具优异加工特性、光学性质、低温热封性、耐化学性、交链发泡性，广泛应用于温室棚膜、积层包装膜、农业用膜、一般包装膜、押出及射出发泡、热熔胶等产品应用
EVA树脂用途很广。一般情况下，乙酸乙烯含量在5%以下的EVA，其主要产品是薄膜、电线电缆、LDPE改性剂、胶粘剂等；乙酸乙烯含量在5%~10% 的EVA产品为弹性薄膜等；乙酸乙烯含量在20~28%的EVA，主要用于热熔粘合剂和涂层制品；乙酸乙烯含量在5%~45%，主要产品为薄膜（包括农用薄膜）和片材，注塑、模塑制品，发泡制品，热熔粘合剂等。如：
（1）薄膜、薄片及层合制品：具有密封性、粘合性、柔软性、强韧性、紧缩性，适合弹性包装薄膜，热收缩薄膜，农用薄膜，食品包装薄膜，层合薄膜，可以用于做聚烯烃层压薄膜的中间层。
（2）一般用品：具有柔韧性，抗环境应力开裂性，耐气候性好的优点，适合工业用材料有电力电线绝缘皮包，家用电器配件，窗密封材料等。
（3）日用杂货类有运动用品，玩具、坐垫、束带、密封容器盖、EVA橡胶足球等。
（4）汽车配件有避震器、挡泥板、车内外装饰配件等。
（5）发泡制品：加压发泡有泡沫塑料拖鞋、凉鞋、建筑材料等。注塑发泡有各种工业零部件，女用鞋底，热熔粘合剂等。
Eva Taiwan Plastics 7470M Vinyl-Vinyl Acetate Monomer VA content 26% foamed grade Eva is a copolymer of Ethylene and VA (Vinyl Acetate Monomer) , with elastic and thermal bonding temperature, internal structure, penetration and other characteristics are also different. Not only for high value-added products such as solar panels, but also for a wide range of applications such as soles, life jackets and other areas of vinyl-vinyl acetate copolymer (Eva) to provide up to 33% VA content, to meet the diverse needs of customers. Eva has excellent processing characteristics, optical properties, low temperature heat sealing, chemical resistance, chain foaming, widely used in greenhouse film, laminated packaging film, agricultural film, general packaging film, extrusion and injection foaming, hot-melt adhesives and other products use EVA resin is very wide. In general, EVA with ethylene acetate content below 5% is mainly used for film, Wire and cable, LDPE modifier, adhesive, etc. Eva with ethylene acetate content of 20-28% is mainly used for hot-melt adhesives and coating products, while EVA with ethylene acetate content of 5-45% is mainly used for film (including agricultural film) and sheet, injection and molding products, foaming products, hot melt adhesives, etc. . Such as:
(1) film, sheet and laminated products: with sealing, adhesion, flexibility, strong toughness, compression, suitable for elastic packaging film, heat-shrinkable film, agricultural film, food packaging film, the laminated film can be used as an intermediate layer of the polyolefin laminated film. (2) general articles: with the advantages of flexibility, resistance to environmental stress cracking, good weather resistance, suitable for industrial materials such as power line insulation leather bags, home appliances accessories, window sealing materials. (3) daily groceries include sporting goods, toys, cushions, straps, sealed container covers, Eva rubber football, etc. . (4) automobile accessories include shock absorber, Fender, interior and exterior decoration accessories, etc. . (5) foamed products: pressure foamed with foam plastic slippers, sandals, building materials, etc. . Injection foam has a variety of industrial parts, women's soles, hot-melt adhesives and so on.
