Abstract
An elastomer-forming composition comprises a convertible organopolysiloxane, a reinforcing silica filler, a chlorinated aromatic acyl peroxide and from 0.1 to 10 pts. by wt. per 100 pts. of siloxane of an additive comprising MgO and/or Al2O3. The siloxanes used preferably contain a major proportion of methyl or methyl and phenyl radicals, any remaining radicals being vinyl and/or higher alkyl radicals; other radicals specified are chlorophenyl, trifluoropropyl and cyanopropyl. Non - reinforcing fillers, e.g. quartz, calcined clay, diatomaceous earth and ZnO, may be used in conjunction with the reinforcing silica filler. In a typical Example (1) a siloxane gum (composed of Me2SiO and MeViSiO units), fume SiO2 and a low M.W. dimethylsiloxane containing Sibonded -OH groups were compounded in a rubber mixer, and the resulting composition was further compounded with 2,4-dichlorobenzoyl peroxide and MgO, and vulcanized under pressure at 115 DEG C. for 5 minutes.
