EVA 在 PVC 电缆料中应用的研究

Studies on the Application of EVA in PVC Cable Compounds

本文对高 VA 含量 EVA 与 S-PVC 的共混以及 EVA 用量和不同增容剂用量与相容性的关系进行了研究。对电缆料的低温性、绝缘性、加工性和耐老化性的研究,确定了电缆配方中的适宜用量。

In this paper,blending of S-PVC with high VA-content EVA and therelationship between contents of EVA and different compatibilizers and compa-tibility were investigated.And,the optimum amount of EVA incorporated inthe cable compound formulations also was determined through the studies onthe low-temperature resistance,insulation properties,processability,and heatageing resistance.
