Description

Polypropylene Glycol Adipate is a synthetic polyester polyol derived from adipic acid and propylene glycol. This versatile chemical intermediate is valued for its role in producing high-performance, flexible polyurethane foams and elastomers with enhanced hydrolytic stability. It is essential for manufacturers in the polyurethane, coatings, and adhesives industries seeking to improve product durability and processing characteristics.

Application

• Polyurethane Foam Production: A key polyol component for manufacturing flexible slabstock and molded foams, providing excellent resilience and comfort.
• Elastomer Systems: Used in castable and thermoplastic polyurethane (TPU) elastomers for applications requiring flexibility, toughness, and resistance to hydrolysis.
• Coatings & Adhesives: Serves as a building block in solvent-borne and high-solids coatings, as well as adhesives and sealants, contributing to film flexibility and adhesion.
• Plasticizer & Modifier: Acts as a polymeric plasticizer and compatibility enhancer in PVC and other polymer blends to improve low-temperature performance.
• Lubricant Base Stock: Utilized in formulating synthetic lubricants and functional fluids due to its thermal stability and low pour point.

Quality Control

Our Polypropylene Glycol Adipate is manufactured under a strict quality management system. Each batch is tested to ensure consistent hydroxyl value, acid value, viscosity, and moisture content, meeting the specifications required for high-performance polyurethane applications. Certificates of Analysis (COA) documenting these parameters are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
