Organopolysiloxane compositions useful for the pressure-free crosslinking of silicone rubber extrudates are crosslinked by specific organic peroxide compounds

摘要

Organopolysiloxane compositions (OPSC) are obtained from an organopolysiloxane and a crosslinking agent containing bis-4-methylbenzoylperoxide (PMBP) and one or more compounds selected from: benzoylperoxide, dicumylperoxide, 2,5-dimethylhexane-2.5-di-t-butyl peroxide and di-t-butyl peroxide.
