UseStearic acid plays an important role in the synthesis and processing of rubber. Stearic acid is a widely used vulcanizing agent in natural rubber, synthetic rubber and latex, and can also be used as a plasticizer and softener. Stearic acid is added as an emulsifier in the production of synthetic rubber.Foam rubberWhen, stearic acid can be used as a foaming agent, stearic acid can also be used as a release agent for rubber products.
