The CRs™ system allows previously vulcanized rubber crumbs to become chemically reactivated to create a new compounding material.
CRs™ can be used for SBR, PBR, IR, Butyl and EPDM rubber; it can be used with any vulcanized rubber crumbs.
CRs™ uses standard industry tire manufacturing machinery and requires no new capital investment.
