摘要：
This invention relates to an expandable curing bladder (10) for use in curing rubber products. The bladder comprises an inner layer (12) and an outer layer (14). The inner layer (12) comprises a rubber composition comprising, based on parts weight per 100 parts by weight rubber (phr), an isobutylene copolymer rubber selected from butyl rubber and/or halobutyl rubber,
wherein said butyl rubber comprises a copolymer of isobutylene and isoprene which contains from about 0.5 to about 5 weight percent units derived from isoprene;
wherein said halobutyl rubber is a halogenated butyl rubber comprising a chlorinated or brominated copolymer of isobutylene and isoprene which contains from about 0.5 to about 5 weight percent units derived from isoprene, and wherein
the outer layer (14) comprises a rubber composition comprising a silicone rubber.
