增塑剂对PVC电缆料电性能的影响

Influences of plasticizers on the electrical properties of PVC cable materials

介绍了DBP、TPP、DOP、TOTM、TCP、DIDP及M - 5 0等增塑剂在不同用量时对PVC电缆料电性能的影响 :随着增塑剂用量的增加 ,PVC电缆料的电性能一般呈下降趋势。实验发现TOTM和TCP两种增塑剂的电性能较优 ,其最佳用量为 35～

Influences of different using amount of plasticizers,such as DBP,TPP,DOP,TOTM,TCP,DIDP and M-50,on the electrical properties of PVC cable materials are introduced.Generally,with the increase of using amount of plasticizers, the electrical properties of PVC cable materials go down.It is found that the electrical property of PVC cable material with TOTM or TCP plasticizer is better,and that the optimum using amount of the above two kinds of plasticizer is 35～40 parts based on 100 parts PVC resin.
