Description

Pentaerythritol Monostearate CAS NO 60130-68-9 is a versatile partial ester derived from pentaerythritol and stearic acid, functioning as a multifunctional non-ionic surfactant and emulsifier. Its unique structure provides excellent lubricity, anti-static properties, and compatibility with a wide range of polymers and oils, making it a critical additive for enhancing material performance. This chemical is essential for manufacturers in the plastics, coatings, and personal care industries seeking to improve product processability, surface finish, and stability.

Application

• Plastic & Polymer Additive: Acts as an internal and external lubricant, mold release agent, and anti-static agent in PVC, polyolefins, and engineering plastics to improve flow and surface quality.
• Synthetic Lubricant & Grease Component: Used as a thickening agent and performance additive in high-temperature greases and synthetic lubricants for industrial machinery.
• Coating & Ink Industry: Serves as a dispersing agent, flow modifier, and anti-settling agent in solvent-based and powder coatings, as well as printing inks.
• Personal Care & Cosmetics: Functions as an opacifier, pearlescent agent, and viscosity modifier in creams, lotions, and hair care products.
• Textile & Fiber Processing: Employed as a spin finish, softener, and anti-static agent in synthetic fiber production and textile finishing.
• Metalworking Fluids: Used as an emulsifier and lubricity additive in cutting oils, drawing compounds, and rust preventatives.
• Adhesive & Sealant Formulation: Improves wetting, dispersion, and stability in various adhesive and sealant systems.
