Title:
FLAME-RETARDANT ELECTRICAL INSULATING COMPOSITION
Document Type and Number:
Japanese Patent JPH02274742
Kind Code:
A
Abstract:
PURPOSE:To prepare a flame-retardant electrical insulating compsn. excellent in the flame retardancy and capable of keeping the mechanical properties and extrusion processability by compounding a polyolefin with an inorg. flame retardant and lead sulfate or sulfite. CONSTITUTION:100 pts.wt. polyolefine is compounded with 50 to 300 pts.wt. inorg. flame retardant and at least 0.5 pt.wt. lead sulfate or sulfite. Examples of said polyolefin include an ethylene-propylene copolymer, ethylene-propylene- diene terpolymer, polyethylene, and ethylene-vinyl acetate copolymer. Examples of said inorg. flame retardant include aluminum hydroxide, magnesium hydroxide, basic magnesium carbonate, calcium hydroxide, and hydrotalcite.
