Description

Butylene Glycol Adipic Acid Polyester is a synthetic polyester polyol derived from the condensation of butylene glycol and adipic acid. This versatile polymer intermediate is valued for its role in creating high-performance, flexible polyurethane foams and elastomers with excellent hydrolytic stability. It is essential for manufacturers in the polyurethane, coatings, and specialty adhesives industries seeking to enhance product durability and processing characteristics.

Application

• Flexible Polyurethane Foams: A key polyol component for producing soft, resilient foams used in automotive seating, furniture, and bedding.
• Coatings and Adhesives: Serves as a building block in solvent-based and high-solids coatings, as well as polyurethane adhesives, providing flexibility and chemical resistance.
• Elastomers: Used in the synthesis of castable and thermoplastic polyurethane (TPU) elastomers for industrial parts, seals, and gaskets.
• Resin Modification: Acts as a plasticizer or modifier for other polymer resins to improve low-temperature flexibility and impact resistance.
• Specialty Intermediates: Employed in the production of more complex polymeric structures for advanced material applications.

Quality Control

Our Butylene Glycol Adipic Acid Polyester is manufactured under a strict quality management system. Each batch is tested against key parameters including hydroxyl value, acid value, viscosity, and water content to ensure consistency and performance for polyurethane applications. Certificates of Analysis (COA) documenting these specifications are available upon request.

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 material is hygroscopic (moisture-sensitive); keep containers tightly sealed when not in use to prevent moisture absorption, which can affect product performance.
