Disproportionated Rosin Extra Grade
CAS No.: 8050-09-7
EINECS No.: 232-475-7
Formula: C19H27COOH
Description
Disproportionated rosins is made of original gum rosin that catalyzed by dehydroabie acid and dihydroabtice acid under the inorganic acid and high temperature, and it finally become a kind of disproportionated product via oxidation & reduction reaction. Disporportionated rosins can be used as emulgator for synthetic rubber manufacturing, it can enhance the finished product’s intensity, thermal endurance, rub resistance and durability. In addition of rubber products, such a material also can be used for coating, adhesive, water-based pressure sensitive adhesive and chewing gum.
