Uses

◆In most sulfur vulcanized elastomers, natural rubber and styrene-butadiene rubber ingredients, used together with thiazole and sulfenamide accelerators as auxiliary accelerators. 

◆The formula activated by accelerator DPG has faster vulcanization speed than the formula activated by thiuram and dithiocarbamate accelerators, and has good anti-reversion, anti-flexing properties, and better storage stability sex.

◆Used as gelling agent in natural rubber and styrene-butadiene rubber latex foaming process. 

◆Mainly used as medium speed accelerator for natural rubber and synthetic rubber. Often used as an active agent for thiazoles, thiurams and sulfenamide accelerators. When the second accelerator of thiazole type accelerator is used, the aging resistance of the vulcanizate decreases, and an appropriate antioxidant must be used.

◆It will cause discoloration, so it is not suitable for white and light-colored rubber products.

◆In chloroprene rubber, it has the functions of plasticizer and shrinkage agent.
