Description

Tdi/ Butylene-Hexamethylene Glycol/ Adipic Acid Copolymer CAS NO 9068-97-7 is a specialized segmented copolymer designed for high-performance polyurethane applications. This engineered material provides a unique balance of flexibility, chemical resistance, and durability, making it a critical component for demanding formulations. It is primarily sought by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for advanced thermoplastic polyurethane (TPU) production.

Application

• High-Performance Polyurethane Coatings: Used as a key polyol component in formulations requiring excellent weatherability, abrasion resistance, and chemical protection for industrial and automotive finishes.
• Thermoplastic Polyurethane (TPU) Elastomers: Serves as a building block for TPUs used in cable jacketing, hoses, films, and industrial belts that demand a combination of toughness and flexibility.
• Adhesives and Sealants: Imparts enhanced bonding strength, elasticity, and durability to polyurethane-based adhesives and sealants for construction and automotive assembly.
• Elastomeric Fibers and Spandex: Can be utilized in the synthesis of elastic fibers requiring specific soft segment characteristics for textile applications.
• Specialty Resins and Binders: Acts as a polymeric modifier in resin systems to improve impact resistance and flexibility in composite materials.

Quality Control

Our Tdi/ Butylene-Hexamethylene Glycol/ Adipic Acid Copolymer is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistency in hydroxyl value, acid value, viscosity, and molecular weight distribution. Certificates of Analysis (COA) documenting these key specifications are available upon request to support your quality assurance and regulatory compliance needs.

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). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent moisture absorption, which can affect product performance.
