Abstract
PURPOSE: Titled composition, easy of casting and impregnation, and capable of forming a highly electrical-insulating and flame-retardant rubber by cusing, which is prepared by compounding a thermosetting elastic material with a specified amount of a hydrated alumina together with a specified amount of magnesium hydroxide.
CONSTITUTION: (A) 100pts.wt. of a thermosetting elastic material (a primary component of a liquid rubber), comprising an isocyanate prepolymer, obtained by the polymerization of a hydrogenated polyhydroxy-butadiene, castor oil (a curing agent for said polyer) and an isocyanate compound of the formula (wherein R1, R2 and R3 are each a lower alkyl; n is 1W4), is compounded with (B) 60W150pts.wt. of hydrated alumina (Al2O3.3H2O) and (C) 5W30pts.wt. of magnesium hydroxide.
