Title:
FLAME-RETARDANT ELECTRICALLY INSULATING COMPOSITION
Document Type and Number:
Japanese Patent JPH01115945
Kind Code:
A
Abstract:
PURPOSE:To obtain the above composition having high flame retardance and suitable as an electrical insulator, without adding a large amount of inorganic flame retardant, by using a frit as a flame-retarding assistant. CONSTITUTION:The objective composition is produced by compounding 100pts. wt. of a polyolefin (e.g., polyethylene or ethylene-propylene copolymer) with (A) 50-300pts.wt. of an inorganic hydrate (e.g., aluminum hydroxide) and (B) 5-50pts.wt. of frit such as lead potassium frit and borosilicate frit which is a homogeneous inorganic glass melting at high temperature and solidifying at normal temperature.
