Description

Polydiethylene Glycol Adipate is a synthetic polyester derived from diethylene glycol and adipic acid, functioning as a versatile polymeric plasticizer and intermediate. This compound is valued for its ability to impart flexibility, low-temperature performance, and compatibility in various polymer matrices. It is essential for formulators and manufacturers in the plastics, coatings, and specialty chemical industries seeking to modify material properties.

Application

• Primary Plasticizer for PVC, polyurethanes, and other polymers to enhance flexibility and durability.
• Intermediate in the synthesis of specialized polyesters, polyols, and urethane prepolymers.
• Co-Additive in sealants, adhesives, and elastomers to improve low-temperature performance and processing.
• Functional Fluid component in lubricants and hydraulic fluids where ester stability is required.
• Film Former in coatings and inks, contributing to adhesion and film flexibility.
• Compatibilizer in polymer blends to aid in the dispersion of fillers and other additives.

Quality Control

Our Polydiethylene Glycol Adipate is produced under a rigorous quality management system. Each batch is tested against key parameters including acid value, hydroxyl value, viscosity, and color to ensure consistency and performance. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee compliance with your 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 material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product properties.
