Description

Adipic Acid-Ethyleneglycol-Propyleneglycol-Trimethylolpropane Copolymer is a specialized polyester polyol copolymer designed for high-performance polymer synthesis. This compound matters for its ability to impart specific mechanical properties, chemical resistance, and flexibility to final polymeric materials. It is primarily needed by manufacturers in the polyurethane, coatings, adhesives, and specialty resin industries seeking tailored polymer backbones.

Application

• Polyurethane Elastomers & Foams: Serves as a key polyol component for producing flexible and rigid foams, as well as elastomers with enhanced toughness and hydrolytic stability.
• High-Performance Coatings & Paints: Used in the formulation of alkyd resins and polyester-based coatings, contributing to improved film flexibility, adhesion, and durability.
• Adhesives & Sealants: Acts as a building block in hot-melt and reactive polyurethane adhesive systems, providing strong bonding and resistance to environmental stress.
• Specialty Plasticizers: Employed in the synthesis of polymeric plasticizers for PVC and other polymers, offering low volatility and improved permanence.
• Composite Materials: Utilized as a matrix resin or modifier in fiber-reinforced plastics (FRP) and other composite applications.
• Synthetic Lubricants & Hydraulic Fluids: Functions as a base fluid or viscosity modifier in the production of ester-based lubricants.

Quality Control

Our Adipic Acid-Ethyleneglycol-Propyleneglycol-Trimethylolpropane Copolymer undergoes rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Key parameters such as hydroxyl value, acid value, viscosity, and water content are strictly monitored. Certificates of Analysis (COA) documenting full specifications are available upon request.

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) and must be kept under a dry inert atmosphere (e.g., nitrogen) after opening to prevent moisture absorption and degradation.
