Description

Oxirane, methyl-, polymer with oxirane, ether with 1,2,3-propanetriol (3:1), polymer with 2,4-diisocyanato-1-methylbenzene and α-hydro-ω-hydroxypoly[ oxy(methyl-1,2-ethanediyl)] ether with 2-ethyl-2-(hydroxymethyl)-1,3-propanediol is a specialized polyether-polyurethane block copolymer designed for high-performance applications. This advanced polymer offers a unique combination of flexibility, toughness, and chemical resistance derived from its complex polyol and isocyanate-based structure. It is essential for formulators and manufacturers in industries requiring durable, customizable polymeric materials for coatings, adhesives, and elastomers.

Application

• High-Performance Coatings: Used as a key resin or modifier in industrial, automotive, and protective coatings to enhance flexibility, adhesion, and chemical resistance.
• Specialty Adhesives & Sealants: Serves as a base polymer for formulating flexible, durable adhesives and sealants with strong bonding properties.
• Elastomer Production: Acts as a prepolymer or curative in the manufacture of polyurethane and polyurea elastomers for gaskets, wheels, and impact-absorbing components.
• Composite Materials: Utilized as a matrix or toughening agent in fiber-reinforced composites to improve impact strength and stress dissipation.
• Encapsulation & Potting Compounds: Employed in electronics and electrical applications to protect sensitive components, offering good dielectric properties and environmental sealing.
• Textile & Leather Finishing: Functions as a durable, flexible coating or finishing agent for synthetic leather, waterproof fabrics, and technical textiles.

Quality Control

Our polyether-polyurethane block copolymer is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistent performance characteristics such as NCO content, viscosity, hydroxyl value, and molecular weight distribution. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and should be stored in a cool, dry place at room temperature (15-25°C). Ensure containers are kept sealed when not in use to prevent moisture absorption and potential premature reaction. Store away from heat, sparks, and open flame.
