Stearic acid, octadecanoic acid, white waxy transparent solid Or yellowish waxy solid. Can be dispersed into powder with slight butter smell. Slightly soluble in cold water, soluble in alcohol, acetone, easily soluble in benzene, chloroform, ether, carbon tetrachloride, carbon disulfide, amyl acetate and toluene, etc.
According to the supply of stearic acid, stearic acid is widely used in the plastics and rubber industries, and its functions are as follows:
Stearic acid is widely used in PVC Manufacturing of plastic pipes, plates, profiles and films. It is a PVC heat stabilizer with good lubricity and good light and heat stabilization. In the selection of PVC pipes, stearic acid helps prevent “scorching” during processing. It is an effective heat stabilizer added in PVC film processing and can prevent the finished product from being exposed to five types of vulcanization. Film color marking.
Stearic acid plays an important role in the synthesis and processing of rubber. Stearic acid is a widely used vulcanization activator in natural rubber, synthetic rubber and latex. It can also be used as a plasticizer and softener. In the process of producing synthetic rubber, stearic acid needs to be added as an emulsifier. When manufacturing foam rubber, stearic acid can be used as a foaming agent. Stearic acid can also be used as a release agent for rubber products.
