Application
In the synthetic rubber industry, DPR is used as emulsifier in the producing of various product including styrene-butadiene rubber, chloroprene rubber, acrylonitrile-butadiene rubber and acrylonitrile-butadiene-styrene rubber.
Using DPR as an emulsifier, rubber product will improve in cohesion, the endurance to heat will increase for 25%. The endurance to both abrasion and laceration of this rubber is better than ordinary styrene-butadiene rubber. The cohesion will be greatly enhanced if blending with natural rubber.
DPR can be also used for important component of potassium soaps which serve as emulsifiers to improve and strengthen the quality of synthetic rubbers, a raw material for making adhesives, water-based PSA, pigment, and chewing gum
