Description

Hexanedioic Acid Polymer With 2-Ethyl-2(Hydroxymethyl)-1,3-Propanediol, .Alpha.-Hydro-.Omega.-Hydroxypoly(Oxy-1,2-Ethanediyl) And 2,2'-Oxybis[Ethanol] is a specialized, branched polyester polyol used as a high-performance polymeric intermediate. This compound is valued for its ability to impart flexibility, toughness, and specific rheological properties to final polymer networks. It is primarily sought by formulators in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in polyurethane foam production.

Application

• Polyurethane Elastomers: Serves as a key soft segment polyol for producing flexible, durable, and abrasion-resistant elastomers used in industrial wheels, rollers, and gaskets.
• Coatings and Paints: Used in high-performance polyurethane coatings to enhance flexibility, adhesion, and chemical resistance for automotive, industrial, and protective finishes.
• Adhesives and Sealants: Incorporated to improve the toughness, elongation, and low-temperature performance of polyurethane-based adhesives and sealants.
• Flexible Foams: Acts as a modifying polyol in the formulation of flexible polyurethane foams, influencing cell structure and physical properties.
• Resin Modification: Utilized as a reactive modifier in various polymer systems to tailor viscosity, crosslink density, and final material properties.

Quality Control

Our polyester polyol is manufactured under a strict quality management system. Each batch undergoes comprehensive analysis to ensure consistency in hydroxyl value, acid value, viscosity, and moisture content. Certificates of Analysis (COA) documenting these key parameters are provided with every shipment to guarantee product integrity and support your formulation process.

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 absorption of atmospheric moisture, which can affect product performance.
