Abstract

1303432 High-voltage insulating compositions RAYCHEM Ltd 22 April 1970 [22 Jan 1969] 3582/69 Headings C3P and C3T Insulating materials comprise a polymer and an anti-tracking filler system comprising (a) at least 25% of alumina trihydrate and (b) 3 to 20% of a silane-treated silica filler, based on the weight of polymer and filler system. Specified polymers are polyethylene, polypropylene, ethylene/propylene/nonconjugated diene terpolymers, copolymers of ethylene with propylene, vinyl acetate or ethyl acrylate, chlorosulphonated polyethylene, chlorosulphonated polypropylene and silicone rubbers. Many suitable silanes are listed. The compositions may also contain flame retardants, reinforcing fillers and pigments, and may be cross-linked and rendered heat-recoverable, e.g. as tubes for cable connections and caps for cable terminations. Examples describe cross-linkable compositions comprising polyethylene, alumina trihydrate and triallyl cyanurate together with (1 and 3) ethylene/propylene/dicyclopentadiene terpolymer, polymerized tetrahydroquinoline, ferric oxide, dimethyl dichlorosilane-treated silica aerogel and (2) ethylene/ethyl acrylate copolymer.
