Description

Hexanedioic Acid, Polymer With 1,4-Butanediol And 1,2-Ethanediol is a high-performance, aliphatic polyester polyol copolymer derived from adipic acid, 1,4-butanediol, and ethylene glycol. This versatile polymer is engineered to deliver excellent mechanical properties, flexibility, and chemical resistance for advanced material formulations. It is a critical raw material for manufacturers in the polyurethane, coatings, adhesives, and specialty elastomers industries seeking to enhance product durability and performance.

Application

• Polyurethane Elastomers & Thermoplastic Polyurethanes (TPU): Serves as a key soft segment polyol for producing high-resilience, abrasion-resistant, and hydrolytically stable elastomers used in industrial wheels, seals, and automotive parts.
• Coatings & Adhesives: Imparts flexibility, adhesion, and chemical resistance to high-performance coatings for textiles, plastics, and metals, as well as structural and laminating adhesives.
• Resins for Casting & Encapsulation: Used in formulating durable, low-viscosity casting resins for electronic encapsulation, potting compounds, and industrial mold making.
• Synthetic Leather & Artificial Leather Finishes: Provides the necessary softness, tensile strength, and processing characteristics for high-quality synthetic leather substrates and finishes.
• Sealants & Caulks: A fundamental component in formulating flexible, long-lasting polyurethane-based sealants for construction and automotive applications.
• Fiber & Textile Treatment: Employed in coatings and treatments for technical textiles to enhance water resistance, durability, and feel.
