Description

Hexanedioic Acid, Polymer With 2-Ethyl-2-(Hydroxymethyl)-1,3-Propanediol is a specialized polyester polyol derived from adipic acid and trimethylolpropane. This polymer is valued for its role as a key building block in the synthesis of high-performance polyurethane resins, contributing to enhanced flexibility, chemical resistance, and durability in the final product. It is an essential raw material for formulators and manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to develop advanced polymeric materials.

Application

• Polyurethane Resins: Serves as a core polyol component for producing flexible and rigid PU foams, coatings, and adhesives.
• Industrial Coatings: Used in the formulation of high-performance protective coatings for automotive, marine, and industrial equipment, offering excellent weatherability and mechanical properties.
• Adhesives & Sealants: Imparts toughness and adhesion in specialty adhesives, sealants, and potting compounds.
• Elastomers: A key ingredient in the production of castable and thermoplastic polyurethane elastomers for gaskets, wheels, and industrial parts.
• Resin Modification: Employed as a modifier to improve the flexibility and impact resistance of other polymer systems like alkyds and polyesters.
