Description

Hexanedioic Acid, Polymer With 2,2-Bis(Hydroxymethyl)-1,3-Propanediol, Octadecanoate is a high-performance polymeric ester, specifically a polyol ester, derived from adipic acid, pentaerythritol, and stearic acid. This specialized polymer is engineered to deliver exceptional lubricity, thermal stability, and compatibility, making it a critical functional additive in advanced formulations. It is primarily sought by manufacturers in the lubricants, coatings, plastics, and personal care industries seeking to enhance product performance and durability.

Application

• Synthetic Lubricant Base Stock & Additive: Used as a high-performance base fluid or viscosity modifier in synthetic engine oils, compressor oils, and gear oils due to its excellent thermal-oxidative stability and low-temperature fluidity.
• Polymer Plasticizer & Modifier: Acts as an internal lubricant and processing aid in PVC, polyurethanes, and other polymers to improve flexibility, reduce melt viscosity, and enhance flow properties during extrusion and molding.
• Coating & Ink Additive: Imparts slip, mar-resistance, and improved leveling in industrial paints, powder coatings, and printing inks, contributing to a superior final finish.
• Personal Care & Cosmetic Ingredient: Functions as an emollient, skin-conditioning agent, and thickener in creams, lotions, and lipsticks, providing a smooth, non-greasy feel.
• Metalworking Fluid Component: Serves as a lubricity agent and corrosion inhibitor in cutting, grinding, and drawing fluids, protecting tools and workpieces.
• Adhesive & Sealant Formulation: Enhances flexibility, adhesion, and weatherability in high-performance sealants, caulks, and adhesive systems.
