Rosin in the rubber industry

In the rubber industry, the rosin used as softeners to make soft rubber, and easy-to-pinch, and easy-to-filler dispersion, given rubber and plastic in order to facilitate the process in the future with spiral out. In addition, the pigment dispersion can help to make the surface smooth products. Rosin with 2-6% of the rubber to increase its tear strength and flexibility. In the synthetic rubber industry, such as styrene-butadiene and chloroprene, as well as acrylonitrile-butadiene-acrylonitrile butadiene - styrene rubber production are used to make soap potassium rosin disproportionation emulsifier. Since the 1970s, countries around the world each year for synthetic rubber rosin area of the world's rosin output by around 20%. Disproportionated rosin emulsifier used to make rubber can enhance the bonding strength, heat-resistant strength can be increased by 25%, the wear and tear strength than the strength of the general good SBR. And natural rubber mixing, the performance bond is a very significant improvement.
