In hard for products, pvc film additives can be divided into: stabilizers, impact modified agent, lubricant, processing aid. To assistant requirements can be divided into three aspects: - ensure PVC in 100% of plasticizing degrees is not excessive decomposition. That is to ensure that PVC products in the mechanical properties of the optimal plasticizing degrees, does not decompose or less decomposition. - should guarantee high polymerization degree PVC processing, improve the quality and grade of PVC products. PVC polymerization degree is higher, the products of the higher tensile strength, impact strength, the higher the vicat softening point is higher, the higher the hardness.
