EVA 1、***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；2、***乙烯含量在5%~10%的EVA产品为弹性薄膜等；3、***乙烯含量在20~28%的EVA，主要用于热熔粘合剂和涂层制品；EVA是由LLDPE（线性低密度聚乙烯）和醋酸（VA）共聚而成。
EVA 1, EVA with ethylene acetate content below 5%, its main products are film, wire and cable, LDPE modifier, adhesive and so on; 2, ethylene acetate content in 5%~10% EVA product is elastic film, 3, ethylene acetate content in 20~28% EVA, mainly used in hot melt adhesives and coating products; EVA is from LLDPE (linear low density) Polythene) and acetic acid (VA) copolymerization.

LLDPE也是通过化学改性得来的。它是在乙烯聚合中引入丁烯、己烯、辛烯等少量的a-烯烃类单体而形成的共聚物。它具有与HDPE类似的分子构型，但降低了密度和结晶度。LLDPE有良好的耐环境应力开裂性，其机械性能也优于LDPE，因此，其应用范围也相应地扩大了。而氯化聚乙烯（CPE）也是化学改性的产物。
LLDPE is also chemically modified. It is a copolymer formed in ethylene polymerization by introducing a ***all amount of a- olefin monomers, such as butene, hexene and octene. It has a molecular configuration similar to HDPE, but reduces the density and crystallinity. LLDPE has good resistance to environmental stress cracking, and its mechanical properties are superior to LDPE. Therefore, its application scope has expanded correspondingly. Chlorinated polyethylene (CPE) is also a product of chemical modification.

HDPE通过氯化后的产物。氯（CL）部分取代HDPE分子中的氢（H），使分子受到结晶性***，从而使它变得更柔软，并有一定的弹性。它不仅可以用挤出或注塑等方法加工成CPE制品，广泛用于建筑、电器等方面，而且CPE本身成为一种优良的改性剂，可以通过物理共混的方法改善PE材料的阻燃性和PVC材料的抗冲击性。
HDPE passes the product after chlorination. Chlorine (CL) partially replaces the hydrogen (H) in the HDPE molecule, causing the molecules to be destroyed by crystallization, making it softer and more flexible. It can not only be processed into CPE products by extrusion or injection molding, but also widely used in c***truction and electrical appliances, and CPE itself becomes a fine modifier. It can improve the flame retardancy of PE materials and the impact resistance of PVC materials by physical blending.

PA66的收缩率在1%~2%之间，加入玻璃纤维添加剂可以将收缩率降低到0.2%~1% 。收缩率在流程方向和与流程方向相垂直方向上的相异是较大的。PA66对许多溶剂具有抗溶性，但对酸和其它一些氯化剂的抵抗力较弱。
The shrinkage of PA66 is between 1%~2%, and the addition of glass fiber can reduce the shrinkage to 0.2%~1%. The shrinkage rate is different from that in the vertical direction of the flow direction. PA66 is resistant to many solvents, but is less resistant to acids and other chlorinated agents.
