PRODUCT DESCRIPTION

Stearic acid is a versatile fatty acid additive widely used in PVC processing as an internal/external lubricant and release agent. Its high purity ensures excellent compatibility with PVC resins and other additives, reducing friction during melt processing and preventing adhesion to molds or machinery. This additive improves flow properties, enhances surface finish, and stabilizes processing temperatures, making it essential for efficient PVC production.
