Stearic acid is widely used in the manufacture of PVC plastic pipes, plates, profiles and films. Is PVC heat stabilizer, has good lubricity and good light, heat stability.
In the plastic PVC pipe, stearic acid helps to prevent the processing process of "coking", in the PVC film processing added is an effective heat stabilizer, at the same time can prevent sudden placed in the sulfide caused by the discoloration of the finished film rubber industry stearic acid plays an important role in the synthesis and processing of rubber.
Stearic acid is a widely used curing active agent in natural rubber, synthetic rubber and latex, and can also be used as plasticizer and softener. In the process of producing synthetic rubber, stearic acid should be used as emulsifier. In the process of making foam rubber, stearic acid can be used as foaming agent, and stearic acid can also be used as mold release agent of rubber products.
