  • Continuously cured EPDM used in various dampening applications including vehicle axle cords
    Patent number: 8393626
    Abstract: The present invention generally relates to the use of EPDM (ethylene-propylene diene monomer) polymer compounds used in place of NR (natural rubber), SBR (styrene butadiene rubber), polyisoprene and other polymers in energy absorption elastomeric systems. In one embodiment a method of continuously manufacturing an EPDM based compound cured via a peroxide based cure system and used in an energy absorption elastomeric system is disclosed. The method includes the steps of forming a continuous part from a compound based on ethylene-propylene diene terpolymer and then curing the part via a continuous process and optionally cutting the final part to the appropriate length. Various advantages are achieved via the use of peroxide cured EPDM as replacements for NR, SBR, polyisoprene and other polymers.
