Styrene-butadiene rubber (SBR), polydimethyl siloxane rubber (MQ) and
their blends cure with sulphur, peroxide and combinations of both syst
ems, Cure characteristics and vulcanizate properties are compared, The
best results are obtained with SBR/MQ = 80/20 blends, For determining
(M) over bar(c) and crosslink density v, stress-strain measurements,
Mooney-Rivlin parameters and new equations are used. They are in good
agreement with the already known and recognized equations. Some torn v
ulcanizate surfaces of such blends were studied by SEM.
