Description

Dipentaerythritol Hexastearat is a high-purity, fully esterified derivative of dipentaerythritol and stearic acid. This compound serves as a highly effective multifunctional additive, providing excellent lubricity, release properties, and thermal stability to polymer systems. It is primarily utilized by formulators in the plastics, coatings, and specialty chemical industries seeking to enhance processing characteristics and final product performance.

Application

• As a high-performance internal and external lubricant for PVC, polyolefins, and engineering plastics to reduce melt viscosity and improve mold release.
• As a processing aid and anti-blocking agent in plastic films and sheets to prevent adhesion during production and storage.
• As a viscosity modifier and flow promoter in hot-melt adhesives, sealants, and specialty coatings.
• As a texturizing and conditioning agent in personal care products like lipsticks and creams.
• As a waterproofing and hydrophobic agent in surface treatments for textiles and paper.
• As a compatibilizer and dispersing aid for pigments and fillers in masterbatch production.
• As a raw material for the synthesis of more complex polymeric plasticizers and stabilizers.
