What is Rubber Antioxidant TMQ RD CAS 26780-96-1?

Rubber Antioxidant TMQ, also called RD, is a polymeric amine antidegradant based on 2,2,4-trimethyl-1,2-dihydroquinoline. It is used in rubber compounds to improve resistance to heat and oxidative aging.

Are TMQ and RD the same rubber antioxidant?

Yes. TMQ and RD are common names for the same polymeric quinoline antioxidant identified by CAS 26780-96-1. The supplied grade should still be confirmed by physical form, softening range and batch release data.

Is TMQ suitable for light-coloured or non-staining rubber goods?

TMQ is an amine antioxidant and can contribute to discoloration in light-coloured or contact products. It is normally evaluated for dark rubber compounds, and suitability should be confirmed on the finished formulation and service conditions.

Which TMQ specifications should a rubber compounder confirm?

Confirm appearance, softening point, heat loss, ash, ethanol-insoluble content and, where relevant, the dimer/trimer/tetramer distribution. Commercial grades commonly have a softening point around 80-100 deg C, but acceptance should follow the approved compound specification.
