Description

Carbonic Acid, Diphenyl Ester, Polymer With 1,6-Hexanediol, 5-Isocyanato-1-(Isocyanatomethyl)-1,3,3-Trimethylcyclohexane And 2-Oxepanone CAS NO 87836-98-4 is a specialized poly(carbonate-urethane) copolymer engineered for high-performance applications. This advanced polymer offers a unique combination of toughness, chemical resistance, and processability derived from its segmented structure. It is primarily sought by formulators and manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for the development of specialty medical-grade polymers and high-durability films.

Application

• High-Performance Coatings: Used as a binder in industrial, automotive, and marine coatings requiring exceptional weatherability, abrasion resistance, and chemical stability.
• Advanced Adhesives & Sealants: Serves as a key polymer component in structural adhesives and flexible sealants where strong bonding and durability under stress are critical.
• Specialty Elastomers and Thermoplastic Polyurethanes (TPU): Imparts elasticity, resilience, and hydrolytic stability to molded or extruded elastomeric components.
• Medical Device Polymers: Suitable for formulating biocompatible polymers used in certain medical device applications, subject to rigorous qualification and regulatory compliance.
• Film & Sheet Production: Employed in the manufacture of durable, transparent films for protective layers, membranes, and specialty packaging.
• Fiber & Composite Modification: Acts as a modifier or coating agent for synthetic fibers and composite materials to enhance interfacial adhesion and performance.

Quality Control

Our production of this advanced polymer adheres to strict quality management systems. Each batch is characterized for critical parameters including molecular weight distribution, thermal properties, and functional group content to ensure batch-to-batch consistency. Certificates of Analysis (COA) detailing specific test results are provided and can be tailored to meet customer or regulatory requirements such as ISO 9001 or medical device component guidelines.

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 material is moisture-sensitive (hygroscopic). Keep away from strong acids, bases, and oxidizing agents to prevent degradation of the polymer chains.
