Description

Oxirane, Polymer With 1,3-Diisocyanatomethylbenzene, α-Hydro-ω-Hydroxypoly( Oxy-1,4-Butanediyl) And α-Hydro-ω-Hydroxypoly[ Oxy(Methyl-1,2-Ethanediyl)] is a specialized polyurethane prepolymer or polyol derivative, synthesized from epoxides, isocyanates, and polyether polyols. This compound is engineered to provide a versatile building block for high-performance polymer systems, offering a balance of flexibility, chemical resistance, and adhesion properties. It is primarily utilized by formulators in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product durability and performance. The material is identified by CAS No. 132435-09-7.

Application

• High-Performance Coatings: Used as a key resin component in protective and industrial coatings for metal, concrete, and plastic substrates, providing excellent weatherability and chemical resistance.
• Adhesives & Sealants: Serves as a prepolymer in the formulation of polyurethane-based structural adhesives, sealants, and potting compounds, offering strong bonding and flexibility.
• Elastomer Production: Acts as an intermediate in the manufacture of cast, thermoplastic, or millable polyurethane elastomers for gaskets, wheels, and industrial parts.
• Composite Materials: Utilized as a matrix resin or modifier in fiber-reinforced composites for the automotive and aerospace sectors.
• Waterproofing Membranes: A critical raw material in formulating liquid-applied waterproofing and roofing systems.
• Flexible Foams: Can be employed as a polyol component in the production of specialized flexible polyurethane foams.

Quality Control

Our production of this polyurethane intermediate adheres to strict quality management systems. Each batch undergoes comprehensive analysis to ensure consistency in key parameters such as isocyanate (NCO) content, hydroxyl value, viscosity, and moisture content. Certificates of Analysis (COA) are provided with every shipment, detailing the specific test results against agreed specifications. We support our global partners by ensuring our materials meet relevant industry standards for polymer raw materials.

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 / 59-77°F). This material is hygroscopic (moisture-sensitive) and must be kept under a dry inert atmosphere (e.g., nitrogen blanket) after opening to prevent premature reaction and viscosity increase. Keep away from heat, sparks, and open flame.
