Description

Hexanedioic Acid Polymer With 1,4-Butanediol, 1,2-Ethanediol, .Alpha.-Hydro-.Omega.-Hydroxypoly(Oxy-1,4-Butanediyl) And 1,1'-Methylenebis(4-Isocyanatobenzene) CAS NO 89097-01-8 is a specialized polyurethane prepolymer or segmented copolymer based on adipic acid, glycols, poly(tetramethylene ether) glycol (PTMEG), and MDI. This engineered material matters for its unique balance of flexibility, toughness, and chemical resistance, derived from its segmented structure combining soft polyether/ester blocks with hard urethane segments. It is primarily needed by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking high-performance polymer components.

Application

• High-Performance Elastomers and Thermoplastic Polyurethanes (TPU): Used as a key intermediate for manufacturing flexible, durable, and abrasion-resistant elastomeric products.
• Coatings and Paints: Serves as a resin component in protective and decorative coatings, offering excellent adhesion, chemical resistance, and weatherability.
• Adhesives and Sealants: Provides strong bonding properties and flexibility in formulated adhesives and sealants for automotive, construction, and industrial assembly.
• Fiber and Textile Finishing: Used in coatings for synthetic fibers and technical textiles to enhance durability, water resistance, and handle.
• Engineering Plastics Modification: Acts as a compatibilizer or impact modifier to improve the toughness and flexibility of rigid polymer blends.
• Medical Device Components: Potential use in biocompatible applications, such as tubing or flexible parts, subject to stringent purity and regulatory compliance.

Quality Control

Our production of this polyurethane polymer adheres to strict quality management systems. Each batch is characterized for critical parameters including NCO content, viscosity, hydroxyl value, and molecular weight distribution to ensure batch-to-batch consistency and performance. Certificates of Analysis (COA) detailing these specifications are available upon request. We support compliance with relevant industry standards for polymer intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Recommended storage temperature is between 15°C and 25°C. Keep away from heat, sparks, and open flames. Moisture-sensitive; keep container tightly sealed to prevent reaction with atmospheric moisture. Store away from strong acids, bases, and oxidizing agents.
