RADIATION VULCANIZATION OF POLYCHOROPRENE RUBBERS

A new vulcanization processes of CR has been studied radiation vulcanization It has been found that CR containing 4phr PFM 4G, 30phr carbon black and 4phr MgO can be vulcanizede at 30～ 50kGy And in that case radiation vulcanized CR rubbers have better physical properties comparing to those of tradiational chemical vulcanized CR rubbers Soinsome case, CR can be vulcanized by radiation instand of chemical methods
