Description

2-Oxepanone, Polymer With 1,1-Methylenebis4-Isocyanatocyclohexane And 2,2-Oxybisethanol is a specialized polyurethane prepolymer or polymer derived from ε-caprolactone, a hydrogenated methylene diphenyl diisocyanate (H12MDI), and diethylene glycol. This material matters for its unique combination of hydrolytic stability, low-temperature flexibility, and excellent mechanical properties, making it a high-performance component in demanding applications. It is primarily needed by formulators and manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in the production of specialty resins and biomedical materials.

Application

• High-Performance Coatings: Used as a key resin component in automotive, industrial, and marine coatings requiring excellent weatherability, chemical resistance, and flexibility.
• Specialty Adhesives & Sealants: Serves as a base polymer for formulating adhesives and sealants with superior bonding strength, durability, and resistance to moisture and environmental stress.
• Medical-Grade Elastomers: Employed in the synthesis of biocompatible polyurethanes for medical devices, tubing, and implants due to its stability and purity potential.
• Flexible & Cast Elastomers: A crucial ingredient in producing cast polyurethane elastomers for rollers, wheels, gaskets, and industrial parts that demand toughness and abrasion resistance.
• Composite Materials: Acts as a matrix resin or modifier in advanced composites to enhance interfacial adhesion and impact performance.
• Fiber & Film Modification: Utilized as a coating or additive to improve the properties of synthetic fibers and films, such as elasticity and dyeability.

Quality Control

Our production of this advanced polymer adheres to strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistent molecular weight distribution, functionality, and purity. Certificates of Analysis (COA) detailing key parameters such as NCO content (if applicable), hydroxyl value, viscosity, and residual monomer levels are provided to guarantee the material meets your specific formulation requirements.

Storage

Preserve in a tightly closed container, protected from light and moisture. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). Keep away from heat sources and incompatible materials such as strong acids, bases, and oxidizing agents. Under these conditions, the product is typically stable for 24 months from the date of manufacture. For long-term storage under inert atmosphere, please contact us for specific recommendations.
