Description

Oxirane, Methyl-, Polymer With 1,3-Diisocyanatomethylbenzene, .Alpha.-Hydro-.Omega.-Hydroxypoly(Oxy-1,4-Butanediyl) And Oxirane is a specialized polyurethane-polyether hybrid polymer, known for its unique combination of flexibility, toughness, and chemical resistance. This compound is engineered to deliver superior performance as a reactive intermediate or a property-enhancing additive in advanced material formulations. It is primarily sought after by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for producing high-performance composites and specialty resins.

Application

• High-Performance Coatings & Paints: Used as a key resin component or crosslinker to enhance durability, chemical resistance, and flexibility in industrial, automotive, and marine coatings.
• Advanced Adhesives & Sealants: Serves as a backbone polymer for formulating structural adhesives, potting compounds, and flexible sealants with excellent adhesion and environmental stability.
• Specialty Elastomers & Urethane Castings: A critical raw material for manufacturing cast polyurethane elastomers, rollers, gaskets, and impact-absorbing components.
• Composite Materials: Incorporated into resin matrices for fiber-reinforced plastics (FRP) to improve interlaminar toughness and impact performance.
• Flexible Foams & Cushioning: Used in the formulation of specialized flexible polyurethane foams requiring tailored mechanical properties.
• Waterproofing & Construction Chemicals: Acts as a modifier in membranes, grouts, and construction sealants to impart elasticity and long-term weatherability.

Quality Control

Our production of this advanced polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as hydroxyl value, isocyanate content, viscosity, and molecular weight distribution are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under a dry atmosphere (e.g., under nitrogen) after initial opening to prevent moisture absorption and premature reaction.
