Description:
FIELD OF THE ART: The present invention relates to a vinyl chloride resin composition for coating electric wires, which is suitable for use as a coating material for electric wires to be used at places where the ambient temperature is high, such as internal wirings of electric or electronic appliances, connecting wirings, various power cables or wirings in automobile engine rooms, or as a coating material for electric wires, the core wire temperature of which is likely to be raised considerably by the application of electric current.
BACKGROUND OF THE INVENTION: Vinyl chloride resin compositions are widely used as coating materials for electric wires for the wirings in various electric or electronic appliances or in automobiles.
Reflecting the improvement in the performance of such appliances and the trend for compact structures in recent years, the coating film is often required to be thin, and consequently vinyl chloride resin compositions are required to have higher heat resistance than before
