Title:

FLAME-RETARDANT ELECTRICAL INSULATION COMPOSITION

Document Type and Number:

Japanese Patent JPH0345637

Kind Code:

A

Abstract:

PURPOSE:To prevent the generation of a halogen gas and improve the flame- retardant properties while maintaining the mechanical properties and extrusion moldability by compounding a polyolefin resin with an inorg. flame retardant and a specific polyacrylonitrile fiber. CONSTITUTION:100 pts.wt. polyolefin resin (e.g. ethylene-vinyl acetate copolymer) is compounded with 50-500 pts.wt. inorg. flame retardant (e.g. magnesium hydroxide), 1-50 pts.wt. polyacrylonitrile fiber having a diameter of 0.2-5mum and a length of 0.5-20mm, and if necessary a crosslinker, an antioxidant, a lubricant, a softener, a dispersant, etc.
