Title:
SEMICONDUCTIVE COMPOSITION MATERIAL AND POWER CABLE
Document Type and Number:
Japanese Patent JP04363808
Kind Code:
A
Abstract:
PURPOSE: To provide a semiconductive composition material with excellent characteristics, excellent heat resistance in particular.
CONSTITUTION: A polymer (EVA-PVC) grafted with vinyl chloride to an ethylene vinyl acetate copolymer and an ethylene vinyl acetate copolymer (EVA) are combined at the blend ratio 90/10-20/80. In a semiconductive composition material combined with a blend composition material 100 pts.wt. added with an adequate quantity of a conductivity imparting agent to the above combination and calcium aluminate or calcium silicate 0.5-20 pts.wt., excellent heat resistance is provided by the calcium aluminate or calcium silicate.
