Gum rosin WW Grade is the transparent light yellow or transparent yellow solid. It is made from pine tree. It is a kind of natural resin, mainly composed of various kinds of resin acids; it can be dissolved easily in many organic solvents, and has special chemical activity.

The Industry grade of Glyceryl Rosinate (a polyol ester of rosin), also called Glycerol Esterof Gum Rosin (GEGR), which is used for specialty industries of adhesives,coating and paints. G-85 also widely used in polymers including EVA, acrylics, polyurethanes, SIS and SBS.

Gum Rosin G90 is the slight yellow or water-white transparent solid, which is made from gum rosin or refined gum rosin through esterification with glycerol; G-90 is good tackifying resin. The Industry grade of Glyceryl Rosinate (a polyol ester of rosin), also called Glycerol Esterof Gum Rosin (GEGR), which is used for specialty industries of adhesives,coating and paints. G-90 also widely used in polymers including EVA, acrylics, polyurethanes, SIS and SBS.

R95 rosin ester are friendly environmental, which is made of the natural colophony tree with light color and low odor. These application properties help formulators to ensure that the applied road markings paint stay in specification from the beginning to the end of the striping job. Rosin Ester is pine-based raw materials,the product allows formulators to improve road marking performance while lessening environmental impact.

ECOPOWER R105 rosin ester are friendly environmental,which is made of the natural colophony tree with light color and low odor.

R100 rosin ester are friendly environmental,which is made of the natural colophony tree with light color and low odor.

Disproportionated rosin (DPR) is compound of dehydroabie acid and dihydroabtice acid, the DPR is processed through catalytic reaction of gum rosin on proper temperature. 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, and 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.
