台湾台塑EVA UE659--UE659是一种高VA含量的乙烯-醋酸乙烯酯共聚物(EVA),具有优异的低温冲击强度、环境应力抗裂性、柔韧性、弹性、透明度和加工性能。它可以被开发用于许多新的应用,并替代软质PVC,
橡胶和其他弹性体。UE659的一个主要应用是与发泡剂和交联剂混合,用于泡沫塑料鞋底的压缩成型或注射成型。UE659的另一个主要应用是与增粘剂和PE蜡混合,制成热熔胶。此外,UE659可以通过注射成型和挤出加工,同时加入添加剂。
UE659 is a high VA content ethylene vinyl acetate copolymer (EVA) with excellent low temperature impact strength, environmental stress crack resistance, flexibility, elasticity, transparency, and processability. It could be developed for many new applications and substitute for flexible PVC,
rubbers, and other elastomers. One of major application of UE659 is mixed with blowing agent and cross-linking agent for compression molding or injection molding of foamed shoe sole. Another major application of UE659 is to mix with tackifier and PE wax to make hot melt adhesive. Besides, UE659 could be processed by injection molding, and extrusion while incorporated with additives.
