Description

Hexanedioic Acid, Polymer With 1,4-Butanediol, Carbonic Acid, 1,6-Hexanediol And 1,1-Methylenebis4-Isocyanatobenzene is a specialized poly(carbonate-urethane) copolymer engineered for high-performance applications. This material matters for its unique balance of durability, flexibility, and chemical resistance derived from its segmented polymer structure. It is primarily needed by manufacturers in the medical device, automotive, and advanced coatings industries seeking robust elastomeric or thermoplastic components.

Application

• Medical Device Components: Used in the production of durable, biocompatible parts such as catheter tubing, pump diaphragms, and surgical instrument housings.
• Automotive Interior & Exterior Parts: Serves as a material for weather-resistant seals, gaskets, and interior trim that requires longevity and aesthetic finish.
• High-Performance Coatings & Adhesives: Formulated into protective coatings for metals, plastics, and textiles, offering excellent adhesion and environmental resistance.
• Industrial Elastomers and Molded Goods: Manufactured into custom-molded parts, rollers, and belts that demand high tensile strength and resilience.
• Wire & Cable Insulation/Jacketing: Provides flexible, flame-retardant, and durable insulation for specialized electrical applications.
• Consumer Goods: Utilized in the production of high-wear items like sports equipment, tool grips, and protective cases.

Quality Control

Our poly(carbonate-urethane) products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with relevant industry standards. Key parameters such as molecular weight distribution, thermal stability, and mechanical properties are strictly monitored. Certificates of Analysis (COA) detailing specific lot characteristics are available upon request, supporting applications in regulated markets.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This polymer is hygroscopic (moisture-sensitive); keep the original packaging sealed to prevent moisture absorption, which can affect processing and final properties. Separate from strong oxidizing agents.
