Description

Poly(1,4-Cyclohexanedimethanol Adipate) is a high-performance, saturated polyester polyol derived from 1,4-cyclohexanedimethanol and adipic acid. This specialized polymer is valued for its excellent hydrolytic stability, low color, and resistance to yellowing, making it a superior choice for demanding applications. It is primarily used by formulators in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in the production of specialty polyurethanes and plasticizers.

Application

• Polyurethane Elastomers and Coatings: Serves as a key polyol component for producing high-performance, flexible, and weatherable PU systems.
• Adhesives and Sealants: Imparts flexibility, adhesion, and durability to hot-melt and reactive adhesive formulations.
• Plasticizers for Specialty Polymers: Used as a polymeric plasticizer to enhance the flexibility and low-temperature performance of PVC, polyurethanes, and other polymers.
• Synthetic Lubricants and Functional Fluids: Acts as a base stock for high-stability lubricants due to its thermal and oxidative resistance.
• Resins for Powder Coatings: Contributes to the formulation of durable, flexible, and corrosion-resistant powder coatings.
• Compatibilizer and Modifier: Used to improve the compatibility and properties in polymer blends and composites.
