WESTCO™ TMQ is a highly effective agent that prevents heat-induced aging and also provides minor protection against ozone and fatigue crack failure. Its major field of application is with black elastomers based on SBR. NR, IR, BR and NBR at loadings of 0.5 to 3.0 phr. It provides excellent heat resistance in peroxide cured NBR and EPDM at 0.25 to 1.0 phr. It is also used in polyethylene that has been cross-linked with peroxide.
