Description

Hexanedioic Acid, Polymer With 1,4-Butanediol, 1,3-Diisocyanatomethylbenzene, 2,2-Dimethyl-1,3-Propanediol And 1,6-Hexanediol CAS NO 71106-51-9 is a high-performance, segmented polyurethane or polyurethane-urea copolymer engineered for superior durability and flexibility. This specialized polymer is valued for its excellent mechanical properties, chemical resistance, and thermal stability, making it a critical component in advanced material formulations. It is primarily sought by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for producing high-grade fibers and specialty plastics.

Application

• High-Performance Coatings: Used in formulating durable protective coatings for automotive, industrial, and marine applications that require abrasion and chemical resistance.
• Advanced Adhesives & Sealants: Serves as a key binder in structural adhesives and flexible sealants, offering strong bonding and environmental stability.
• Engineering Elastomers: A fundamental raw material for manufacturing thermoplastic polyurethane (TPU) elastomers used in cables, hoses, gaskets, and industrial wheels.
• Specialty Fibers: Employed in the production of spandex and other high-elasticity synthetic fibers for the textile industry.
• Medical Device Components: Utilized in biocompatible applications for catheters, tubing, and other flexible medical parts where purity and performance are critical.
• Resin Modifier: Acts as an additive to enhance the toughness, flexibility, and impact resistance of other polymer systems like epoxies and polyesters.

Quality Control

Our production of this advanced polymer adheres to strict quality management systems, ensuring batch-to-batch consistency for critical applications. Quality is verified through parameters including intrinsic viscosity, hydroxyl value, isocyanate content, and thermal transition points. A Certificate of Analysis (COA) detailing specific lot specifications is provided with every shipment. We support compliance with relevant global standards, including REACH and industry-specific material requirements.

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). This polymer is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption, which can affect processing and final properties. Keep away from strong heat sources and open flames.
