Abstract
An elastomeric composition for a curing bladder comprises isobutylene based elastomer, curative and a hydrocarbon polymer modifier comprising monomers selected from the group consisting of piperylenes, cyclic pentadienes, aromatics, limonenes, pinenes, amylenes, and combinations thereof, wherein the cyclic pentadienes comprise at least 10 weight percent of the monomers by total weight of the monomers. Also disclosed are a tire curing bladder made from the elastomeric composition, a tire curing press containing the bladder, a method of making the tire curing bladder, an improvement to the process of making the tire curing bladder to improve processability of the mixture and fatigue life and DeMattia cut growth, a method of making a tire using the tire curing bladder, and an improvement to the process of making a tire to extend a pull point of the curing bladder and/or to reduce the curing time for the tire construct.
