Description

Fatty Acids, C16-18, Esters With Pentaerythritol is a high-performance synthetic ester derived from pentaerythritol and a blend of C16-C18 fatty acids, primarily palmitic and stearic acids. This compound is valued for its excellent thermal stability, lubricity, and hydrophobic properties, making it a versatile intermediate and functional additive. It is essential for formulators and manufacturers in the lubricants, plastics, and personal care industries seeking to enhance product performance and durability.

Application

• Lubricant & Grease Formulation: Acts as a high-performance synthetic base oil and thickener, offering excellent oxidation stability and low-temperature fluidity for industrial and automotive lubricants.
• Polymer & Plastic Additive: Used as an internal and external lubricant and plasticizer in PVC, polyolefins, and engineering plastics to improve processing and surface finish.
• Personal Care & Cosmetics: Serves as an emollient, thickener, and stabilizer in creams, lotions, and stick formulations (e.g., deodorants, lip balms).
• Metalworking Fluids: Functions as a lubricity agent and corrosion inhibitor in synthetic and semi-synthetic cutting and grinding fluids.
• Textile & Fiber Processing: Employed as a softening agent and lubricant for synthetic fibers and yarns to reduce friction during spinning and weaving.
• Adhesives & Sealants: Imparts flexibility and water resistance as a plasticizing agent in hot-melt and solvent-based adhesive systems.
