    摘要: Expandable bladders for use in curing presses for hydrocarbon rubbers, such as pneumatic tires, are a crosslinked elastomer composition including isobutylene repeat units. When PTFE and/or graphite is present, they can be cured with brominated phenolic resins in shorter periods of time. The fluorinated ethylene polymer is added in particulate form and thereafter dispersed throughout the bladder. The fluorinated ethylene polymer may or may not form fibers. The bladders may further include graphite. The bladders generally have enhanced lubricity, reduced adhesion to cured tire innerliners, better resistance to cracking during flexing, and have lower tension set than similar compositions without fluorinated ethylene polymers. The above enhancements allow hydrocarbon rubbers such as tires to be molded with fewer defects caused by abraded or deformed bladders. They also enhance the useful life of the bladder reducing the cost of tire curing.

    摘要: Disclosed are expandable bladders for use in curing presses for rubber compositions such as pneumatic tires. The bladders are a crosslinked elastomer comprising an isobutylene rubbery polymer. The bladder composition includes alkylphenoxypoly(alkyleneoxy)-alkanol which improves the release characteristics of the cured bladder from a tire innerliner cured in contact with said bladder. The improved release characteristics allow rubber compositions such as tires to be molded with fewer defects caused during release of the bladder from the tires or caused by abraded or deformed bladders. The use of alkylphenoxypoly(alkyleneoxy)alkanol also increases the useful life time of the bladder allowing more tires to be cured without changing bladders.
