N,N’-Demethyl-N,N’-diphenyl thiuram disulfide,DDTS,MPTD,CAS 53880-86-7

N,N'-Demethyl-N,N'-diphenyl thiuram disulfide (DDTS, MPTD) is a late-acting accelerator for natural rubber, butadiene rubber, isoprene rubber, n-butadiene rubber and nitrile rubber. It is mainly used as a second accelerator with TMTD, TMTM or zinc dithiocarbamate to improve the processing safety of rubber. It does not pollute, does not change color, and is easy to disperse in the rubber material. It is suitable for light-colored and colored products, short-time fast vulcanization molded products, impregnated products and fabric hanging rubber, etc.
