Pentaerythrityl tetrastearate Cas 115-83-3

1. Plastics Processing: Used in engineering plastics—such as PC, PA66, ABS, PBT, PVC, and PP—as an internal and external lubricant, mold-release agent, and dispersing agent. It reduces friction during processing, enhances the surface gloss of finished products, and improves material flow.
2. Rubber Industry: Functions as a lubricating aid and anti-tack agent, improving the processability of rubber compounds.
3. Cosmetics: Used in lipsticks, paste-based cosmetics, and creams as an emollient and rheology modifier (thickener); it enhances the structural stability of formulations while improving the sensory feel of the product upon application.
4. Other Industrial Applications: Serves as a gloss enhancer for coatings and inks; a lubricating additive for metalworking fluids; and an additive for hot-melt waxes and greases.
