Description

Hexanedioic Acid, Polymer With 1,2-Ethanediol And 1,2-Propanediol is a high-performance, water-soluble polyester polyol derived from adipic acid, ethylene glycol, and propylene glycol. This versatile polymer is valued for its excellent flexibility, hydrolytic stability, and ability to form durable polyurethane and polyester resins. It is a critical raw material for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for producing specialty plastics and fibers.

Application

• Polyurethane Elastomers & Foams: Serves as a key soft segment polyol for manufacturing flexible, resilient, and hydrolysis-resistant polyurethane products.
• Coatings & Surface Finishes: Used in the formulation of high-performance polyurethane coatings for automotive, industrial, and wood finishes, providing excellent adhesion and chemical resistance.
• Adhesives & Sealants: Acts as a base polymer for producing strong, flexible polyurethane adhesives and sealants with good weathering properties.
• Synthetic Leather & Textile Coatings: Imparts softness, durability, and moisture resistance to synthetic leather (PU leather) and textile coatings.
• Engineering Plastics & Resins: Utilized as a modifier or building block in the synthesis of specialty polyester resins and engineering plastics to enhance toughness and processability.
• Footwear & Sporting Goods: A component in polyurethane systems for shoe soles, midsoles, and other molded sporting goods requiring a balance of flexibility and strength.

Quality Control

Our Hexanedioic Acid, Polymer With 1,2-Ethanediol And 1,2-Propanediol is manufactured under a strict quality management system. Each batch is tested to ensure consistent performance in downstream applications, with key parameters including hydroxyl value, acid value, viscosity, and water content. Certificates of Analysis (COA) documenting these specifications are available for every shipment to guarantee traceability and compliance with your formulation requirements.

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