Description

Hexanedioic Acid, Polymer With 1,4-Butanediol And 2-Ethyl-2-(Hydroxymethyl)-1,3-Propanediol is a specialized polyester polyol, a key building block for high-performance polyurethane systems. This branched polymer offers a unique combination of flexibility, hydrolytic stability, and reactivity, making it essential for formulating durable and resilient end-products. It is primarily needed by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for producing flexible foams and specialty resins.

Application

• High-Performance Polyurethane Coatings: Used as a polyol component in two-component (2K) coatings for industrial maintenance, automotive refinish, and protective marine coatings, providing excellent chemical resistance and weatherability.
• Elastomers and Castables: Serves as a key raw material for manufacturing polyurethane elastomers, gaskets, wheels, and rollers, offering a balance of toughness and flexibility.
• Adhesives and Sealants: Imparts strong adhesion, flexibility, and durability to polyurethane-based adhesives and sealants used in construction and automotive assembly.
• Flexible Foam Systems: Can be utilized in the formulation of specialized flexible polyurethane foams requiring enhanced resilience and load-bearing properties.
• Resin Modifiers: Acts as a reactive modifier in other polymer systems to improve impact resistance, flexibility, and adhesion characteristics.

Quality Control

Our production of this polyester polyol adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as hydroxyl value, acid value, viscosity, and water content are rigorously tested. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing all relevant specifications.

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 moisture absorption, which can affect product performance.
