Description

Fatty Acids, C5-10, Esters With Polypentaerythritol is a synthetic ester derived from short-chain fatty acids and a polypentaerythritol core, creating a versatile, high-performance chemical intermediate. This compound is valued for its excellent lubricity, thermal stability, and hydrophobic properties, making it a critical component in advanced formulations. It is primarily utilized by manufacturers in the lubricants, plastics, and specialty chemical industries seeking to enhance product performance and durability. CAS NO 68915-66-2.

Application

• Synthetic Lubricant Base Stocks & Additives: Used as a high-performance base fluid or additive in synthetic engine oils, compressor oils, and hydraulic fluids due to its low volatility and excellent thermal-oxidative stability.
• Polymer & Plastic Additives: Acts as an internal or external lubricant and processing aid in PVC, polyolefins, and engineering plastics to improve flow, mold release, and surface finish.
• Metalworking Fluids: Serves as a key component in synthetic and semi-synthetic cutting, grinding, and drawing fluids, providing lubrication, cooling, and corrosion protection.
• Cosmetic & Personal Care Esters: Functions as an emollient, solvent, or carrier in cosmetic formulations such as creams, lotions, and sunscreens, offering a non-greasy feel and good skin compatibility.
• Specialty Coatings & Inks: Employed as a rheology modifier and leveling agent in high-performance coatings, printing inks, and adhesives to enhance application properties and final film quality.
• Textile & Fiber Lubricants: Used as a spin finish and coning oil for synthetic fibers (e.g., polyester, nylon) to reduce friction and static during high-speed textile manufacturing.
