Description

Poly(1,6-Hexanediol/Neopentyl Glycol-Alt-Adipic Acid) is a high-performance, saturated aliphatic copolyester diol, also known as a polyester polyol. This material is valued for its excellent hydrolytic stability, low viscosity, and superior mechanical properties, making it a critical component in demanding polymer formulations. It is primarily sought by manufacturers in the polyurethane, coatings, and specialty adhesives industries for producing elastomers, sealants, and high-durability finishes.

Application

• Polyurethane Elastomers & Castables: As a key polyol component for producing high-performance TPUs (Thermoplastic Polyurethanes) and cast elastomers with excellent abrasion resistance and low-temperature flexibility.
• Coatings & Surface Finishes: Used in the synthesis of polyester-based polyurethane coatings for automotive, industrial, and wood finishes, offering enhanced weatherability and chemical resistance.
• Adhesives & Sealants: Serves as a building block for high-strength, flexible polyurethane adhesives and sealants used in construction and automotive assembly.
• Resins for Plasticizers: Acts as an intermediate in the production of polymeric plasticizers for PVC, improving permanence and low-temperature performance.
• Specialty Polymer Synthesis: Utilized as a macrodiol in the creation of block copolymers and other advanced polymeric materials requiring precise molecular architecture.

Quality Control

Our production of Poly(1,6-Hexanediol/Neopentyl Glycol-Alt-Adipic Acid) adheres to stringent quality management protocols. Each batch is characterized for critical parameters including hydroxyl value, acid value, viscosity, and molecular weight distribution to ensure consistency and performance. Certificates of Analysis (COA) documenting these specifications are available for every shipment. We support compliance with relevant industry standards for polymer intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C/59-77°F). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from strong oxidizing agents.
