Barium stearate Use and Manufacturing

Uses

Used as high temperature resistant lubricant for machinery and high temperature resistant powder for rubber products. It can be used as a stabilizer and lubricant for polyvinyl chloride. Among all the alkaline earth metal stearates, this product has the best long-term heat resistance. Mainly used for soft transparent film, thin plate, artificial leather and hard plate, tube, etc. It can also be used as high temperature resistant mold release agent and high temperature lubricant for machinery.

Chemical additive used in heat stabilizers for PVC applications
