Description

Carbonic Acid, Diphenyl Ester, Polymer With 1,6-Hexanediol, 5-Isocyanato-1-(Isocyanatomethyl)-1,3,3-Trimethylcyclohexane And 4,4-Methylenebiscyclohexanamine CAS NO 73003-55-1 is a high-performance, cross-linked poly(carbonate-urethane) polymer. This specialty material matters for its exceptional balance of durability, chemical resistance, and processability, making it a critical component in advanced manufacturing. It is primarily needed by industries focused on producing high-strength elastomers, specialty coatings, and engineered thermoplastic polyurethanes for demanding applications.

Application

• High-Performance Elastomers: Used as a key building block in the synthesis of thermoplastic polyurethane (TPU) elastomers requiring superior tensile strength, abrasion resistance, and hydrolysis stability.
• Specialty Coatings and Adhesives: Serves as a resin component in formulating durable, flexible, and chemically resistant industrial coatings, sealants, and high-bond adhesives.
• Automotive Components: Employed in the production of under-the-hood parts, gaskets, and interior components that must withstand temperature fluctuations and exposure to oils and fuels.
• Medical Device Polymers: Utilized in the development of biocompatible polymers for certain medical device applications where strength and stability are paramount.
• Wire and Cable Insulation: Acts as a polymer matrix for creating flexible, flame-retardant, and durable insulation and jacketing materials.
• Industrial Rollers and Belts: A critical raw material for manufacturing long-lasting, non-marking rollers, conveyor belts, and other industrial machinery components.

Quality Control

Our production of this advanced polymer adheres to strict quality management systems, ensuring batch-to-batch consistency for critical performance parameters like molecular weight distribution, isocyanate content, and thermal stability. Quality is verified through a suite of analytical techniques including GPC, FT-IR, and DSC. A comprehensive Certificate of Analysis (COA) detailing key specifications is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (15-25°C/59-77°F). Keep the container tightly sealed under a dry, inert atmosphere (e.g., nitrogen) after opening to prevent moisture absorption and premature polymerization or degradation.
