Disproportionate Rosin RC 101
CAS: 8050-09-7 EINECS: 232-475-7 HS.CODE: 380610
Chemical Properties
Disproportionated rosin (DPR) RC 101 is compound of dehydroabie acid and dihydroabtice acid, the DPR RC 101 is processed through catalytic reaction of gum rosin on proper temperature. In the synthetic rubber industry, Disproportionated rosin DPR RC 101 is used as emulsifier in the producing of various products 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, and the endurance to heat will increase by 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 RC 101 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.
