SEMICONDUCTIVE MATERIAL FOR HIGH VOLTAGE

摘要

PURPOSE: A semiconductive material for high voltage is provided to enhance surface property of coarseness and resistance stability due to repetitive heat hysteresis by reducing content of carbon black. CONSTITUTION: A semiconductive material is produced by compounding matrix resin of 100 weight part, carbon black of 40 to 80 weight part, antioxidant 0.2 to 10 weight part, process compound of 0.1 to 10 weight part, crosslink agent 0.1 to 10 weight part, crosslink compound of 0.1 to 10 weight part. The material is mixed by using a kneader mixer and crosslinked for about 20 minutes at 170 dge.C by using a press. The amount of carbon black is reduced more than 15%.
