Description

Hexanedioic Acid, Polymer With 1,4-Butanediol, 1,2-Ethanediol, 2-Ethyl-2-(Hydroxymethyl)-1,3-Propanediol And α-Hydro-ω-Hydroxypoly( Oxy-1,2-Ethanediyl) is a specialized, multi-component polyester polyol designed for high-performance polymer synthesis. This engineered polymer is critical for creating materials with a precise balance of flexibility, toughness, and chemical resistance. It is primarily utilized by formulators and manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in polyurethane production, where its tailored structure enables superior end-product properties.

Application

• High-Performance Polyurethane Systems: Serves as a key polyol component in the formulation of flexible and rigid foams, elastomers, and coatings, offering controlled reactivity and enhanced physical properties.
• Industrial and Protective Coatings: Used in solvent-borne and high-solids coatings to improve film flexibility, adhesion, and durability against chemicals and weathering.
• Adhesives and Sealants: Imparts excellent adhesion, cohesion, and elastic recovery in construction, automotive, and industrial adhesive formulations.
• Elastomer Production: A vital raw material for casting, thermoplastic, and millable polyurethane elastomers requiring a specific balance of hardness and elongation.
• Resin Modification: Employed as a modifier for other polymer systems (e.g., alkyds, polyesters) to tailor flexibility, impact resistance, and compatibility.
• Specialty Polymer Intermediates: Acts as a building block for synthesizing more complex copolymer structures with targeted functional performance.

Quality Control

Our production of this advanced polyester polyol adheres to strict batch-to-batch consistency protocols. Quality is verified through comprehensive testing of key parameters including hydroxyl value, acid value, viscosity, and water content. Certificates of Analysis (COA) documenting these specifications are provided with every shipment to ensure 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 / 59-77°F). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent moisture absorption, which can affect reactivity and properties.
