Description

Hexanedioic Acid, Polymer With 1,4-Butanediol, 1,6-Hexanediol, 3-Hydroxy-2-(Hydroxymethyl)-2-Methylpropanoic Acid And 1,1-Methylenebis4-Isocyanatocyclohexane CAS NO 71394-28-0 is a specialized aliphatic polyester-polyurethane copolymer engineered for high-performance applications. This polymer is valued for its excellent balance of mechanical strength, chemical resistance, and processing versatility, making it a critical raw material for advanced material formulations. It is primarily sought by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for specialty fiber and film production.

Application

• High-Performance Coatings: Used as a key resin in automotive, industrial, and protective coatings for superior durability, gloss, and chemical resistance.
• Advanced Adhesives & Sealants: Serves as a base polymer for structural adhesives and flexible sealants requiring strong bonding and environmental stability.
• Engineering Elastomers: Formulated into castable or thermoplastic polyurethane (TPU) elastomers for gaskets, rollers, and impact-resistant components.
• Specialty Films and Fibers: Utilized in the production of breathable, waterproof membranes and high-tenacity synthetic fibers.
• Composite Materials: Acts as a matrix or binder in fiber-reinforced composites for the automotive and aerospace sectors.
• 3D Printing Filaments: Suitable for formulating specialty filaments (like flexible TPU) for additive manufacturing.
• Textile Finishing: Applied as a coating or finishing agent to enhance fabric properties like water repellency and abrasion resistance.

Quality Control

Our production of this copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as hydroxyl value, acid value, viscosity, and NCO content (for prepolymer grades) are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing specific test results is provided with each shipment to support your quality assurance protocols.

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). Keep away from heat sources, open flames, and incompatible materials such as strong acids, bases, and oxidizing agents. This material is moisture-sensitive; ensure containers are sealed to prevent absorption of atmospheric moisture.
