Description

1,3-Propanediol, 2-Ethyl-2-(Hydroxymethyl)-, Polymer With 1,3-Diisocyanatomethylbenzene And Methyloxirane is a specialized polyol-based polymer, commonly recognized as a key component in high-performance polyurethane systems. This compound is valued for its ability to impart excellent flexibility, chemical resistance, and durability to final materials. It is primarily sought by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for producing specialty foams and composites.

Application

• Polyurethane Elastomers: Used as a soft segment polyol to create flexible, abrasion-resistant, and durable elastomeric products.
• Protective Coatings & Paints: Serves as a resin component in high-performance industrial and automotive coatings, offering enhanced weatherability and chemical resistance.
• Adhesives & Sealants: A key raw material in formulating polyurethane-based adhesives and sealants with strong bonding properties and flexibility.
• Flexible & Rigid Foams: Employed in the synthesis of specialized polyurethane foams for insulation, cushioning, and composite core applications.
• Composite Materials: Acts as a matrix resin or modifier in fiber-reinforced plastics (FRP) and other composite systems.
• Industrial Casting & Molding: Used in the production of cast polyurethane parts, gaskets, and rollers for machinery.

Quality Control

Our production of this polyether polyol adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot undergoes comprehensive analysis, including hydroxyl value, viscosity, water content, and color determination. Certificates of Analysis (COA) documenting all key specifications are available upon request to support your quality assurance and regulatory compliance needs.

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 product performance. Keep away from heat, sparks, and open flame.
