  • Patent number: 10266680
    Abstract: An ethylene-propylene-diene monomer (EPDM) rubber composition for a sponge in a weather strip is provided. In the EPDM rubber composition free sulfur and 1,6-bis(N,N-dibenzylthiocarbamoyldithio)-hexane (BDBzTH) are included in a EPDM rubber having a pattern viscosity (ML1+8 at 125° C.) value of 90 or more and a content of 5-ethylidene-2-norbornene (ENB) of 9 wt % or more. The EPDM rubber composition can improve compression set and provides a solution to the persistent discoloration problem of the EPDM rubber. Provided herein are EPDM compositions that are useful as a material of a sponge section in a weather strip of a passenger car.
