Description

Pentaerythritol Tetrastearate (Pentaerythrityl Tetrastearate) is a high-performance, fully esterified synthetic wax derived from pentaerythritol and stearic acid. This compound serves as a crucial internal and external lubricant and processing aid, significantly improving the flow properties and surface finish of polymer compounds. It is essential for manufacturers in the plastics, coatings, and personal care industries seeking to enhance product quality and production efficiency.

Application

• Primary internal and external lubricant for PVC, ABS, and various engineering plastics.
• Processing aid to reduce melt viscosity and improve flow in polymer extrusion and injection molding.
• Surface modifier and anti-blocking agent in plastic films and sheets.
• Internal mold release agent for complex molded plastic parts.
• Viscosity modifier and consistency provider in cosmetic stick formulations (e.g., lipsticks, deodorants).
• Water-repellent additive and lubricant in coatings and inks.
• Textile finishing agent to impart softness and improve fiber processing.
• Additive for crayons, pencils, and other wax-based products.
