Description

Adipic Acid, Polyester With 1,3-Butanediol, 2,2-Dimethyl-1,3-Propanediol And 2-Ethyl-2-(Hydroxymethyl)-1,3-Propanediol is a specialized, high-performance polyester polyol resin derived from adipic acid and a blend of diols. This compound is engineered to deliver exceptional hydrolytic stability, flexibility, and chemical resistance in demanding polymer formulations. It is a critical raw material for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product durability and performance.

Application

• High-Performance Polyurethane Coatings: Used as a key polyol component in two-component (2K) polyurethane coatings for automotive, industrial, and marine applications, providing excellent weatherability and mechanical properties.
• Flexible and Rigid Foams: Serves as a building block in the production of polyurethane foams, where its structure contributes to controlled foam density, resilience, and insulation characteristics.
• Adhesives and Sealants: Imparts strong adhesion, flexibility, and resistance to plasticizers and solvents in construction and automotive sealants and adhesives.
• Elastomers and Thermoplastic Polyurethanes (TPU): A vital component in manufacturing cast elastomers, rollers, gaskets, and TPU for wires, cables, and films, offering a balance of toughness and low-temperature flexibility.
• Resins for Composite Materials: Utilized in unsaturated polyester resins or as a modifier to improve the impact resistance and processing of fiber-reinforced composites.
• Synthetic Leather and Textile Coatings: Provides the soft feel, durability, and abrasion resistance required for high-quality synthetic leather (PU leather) and textile coatings.

Quality Control

Our production of Adipic Acid Polyester Polyol adheres to stringent quality management protocols. Each batch is characterized by key parameters including hydroxyl value, acid value, viscosity, and water content to ensure consistency and performance. Certificates of Analysis (COA) documenting these specifications are provided with every shipment. Our quality system is designed to support compliance with relevant global standards for industrial and specialty chemical manufacturing.

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). Keep away from heat, sparks, and open flame. Due to its chemical nature, this polyester polyol should be stored separately from strong acids and oxidizing agents. Under these conditions, the product maintains its specified properties.
