ABSTRACT:
The present invention is directed to a resin composition for electric insulation materials for vehicles such as distributor caps which is prepared by blending a crystalline propylene-ethylene copolymer resin with 3 to 10 wt. % of a glass fiber, 10 to 20 wt. % of talc or mica, 5 to 20 wt. % of silica, 4 to 20 wt. % of modified polyolefin resins, 10 to 30 wt. % of halogen-containing flame retardants and 3 to 15 wt. % of flame retardant auxiliaries. In the resin composition of the present invention, balance is kept in all points of mechanical characteristics, mechanical characteristics at high temperature, electrical characteristics, nitric acid resistance, weld characteristics, blooming resistance, corona resistance and flame retardance.
