Description

Poly[oxy(methyl-1,2-ethanediyl)], α,α',α''- 1,2,3-propanetriyltris[ω-hydroxy-, polymer with 1,3-diisocyanatomethylbenzene and α-hydro-ω-hydroxypoly[ oxy(methyl-1,2-ethanediyl)], isocyanate-terminated is a specialized, high-performance polyurethane prepolymer. This compound is engineered to serve as a critical reactive intermediate, offering a precise balance of flexibility and cross-linking potential for advanced material formulations. It is essential for manufacturers seeking to develop durable, high-performance elastomers, adhesives, and coatings with tailored properties.

Application

• High-Performance Elastomers: A key component in the synthesis of polyurethane (PU) and polyurea elastomers for industrial rollers, seals, and gaskets requiring superior abrasion resistance and dynamic performance.
• Advanced Adhesives & Sealants: Used to formulate high-strength, moisture-curing structural adhesives and sealants for the automotive, aerospace, and construction industries.
• Protective & Functional Coatings: Serves as a backbone for durable, chemical-resistant, and waterproof coatings applied to industrial flooring, pipelines, and marine equipment.
• Composite Materials: Acts as a matrix resin or binder in fiber-reinforced composites, enhancing interlaminar shear strength and environmental durability.
• Footwear and Sporting Goods: Utilized in the production of high-resilience midsoles, ski boots, and other molded components demanding excellent mechanical properties.
• Encapsulation and Potting: Employed in electronic and electrical applications to protect sensitive components from moisture, vibration, and thermal shock.

Quality Control

Our production of this polyurethane prepolymer adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Every lot is characterized for critical parameters including isocyanate (NCO) content, viscosity, and moisture content. Comprehensive Certificates of Analysis (COA) documenting these specifications are provided to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures recommended for polyurethane prepolymers, typically between 15°C and 25°C. Due to its hygroscopic and moisture-sensitive nature, containers must be kept sealed under a dry inert atmosphere (e.g., nitrogen) to prevent premature reaction and gelation. Keep away from heat, sparks, and open flame.
