Rubber compositions such as tire innerliners contain significant amounts of ground, fine size tire curing bladder rubber as a filler. Critical properties such as air retention are not affected and spent or old curing bladder rubber which would otherwise go to a landfill is effectively recycled.

Rubber compositions containing ground curing bladder rubber

Old, spent or worn tires are recycled by removing non-rubber components such as belts, beads, and fabric, and grinding the remaining cured rubber into fine sized particles. The ground particles generally replace equivalent amounts of rubber and additives in various tire formulated components such as tire treads. Good physical properties of the end product are retained.
