Description

Fatty Acids, (C=8-18) And (C=18) Unsatd. Polymers With Adipic Acid And Pentaerythritol is a specialized polymeric ester synthesized from a blend of medium to long-chain fatty acids and pentaerythritol, cross-linked with adipic acid. This chemistry provides a unique balance of hydrophobic character, flexibility, and thermal stability, making it a versatile intermediate and functional additive. It is essential for formulators in the coatings, lubricants, and polymer industries seeking to enhance product performance, durability, and environmental resistance.

Application

• Coatings & Resins: Acts as a reactive diluent, flexibilizer, and cross-linking agent in alkyd resins, polyurethane dispersions, and high-solid coatings to improve film formation, adhesion, and weatherability.
• Lubricants & Greases: Serves as a synthetic base oil or thickening agent, contributing to excellent viscosity index, low-temperature fluidity, and oxidation stability in industrial and automotive lubricants.
• Polymer Modification: Used as a plasticizer or compatibilizer in PVC, rubber compounds, and other polymers to improve processability, impact resistance, and low-temperature performance.
• Adhesives & Sealants: Imparts tack, flexibility, and moisture resistance in hot-melt, pressure-sensitive, and elastomeric sealant formulations.
• Inks: Functions as a resin modifier in printing inks to adjust rheology, enhance gloss, and improve substrate wetting.
• Personal Care & Cosmetics: Employed as an emollient, thickener, or film-forming agent in creams, lotions, and hair care products for its skin-feel and conditioning properties.
