Description

Poly(1,3-Propylene Adipate) is a high-performance, biodegradable polyester polyol derived from 1,3-propanediol and adipic acid. This compound is valued for its excellent flexibility, hydrolytic stability, and compatibility in formulating advanced polymeric materials. It serves as a critical building block for manufacturers in the polyurethane, adhesive, and specialty coatings industries seeking sustainable and high-quality raw materials.

Application

• Polyurethane Elastomers & Foams: As a key soft segment polyol for producing flexible, resilient, and durable PU materials.
• Biodegradable Polymers: As a monomer or prepolymer in the synthesis of compostable plastics and films.
• Adhesives & Sealants: To impart flexibility, adhesion, and moisture resistance in high-performance formulations.
• Specialty Coatings: Used in coatings requiring excellent weatherability, chemical resistance, and mechanical properties.
• Thermoplastic Polyurethanes (TPU): For manufacturing TPUs used in cables, hoses, and industrial belts.
• Resin Modification: As a modifier to enhance the toughness and impact resistance of other polymer systems.

Quality Control

Our Poly(1,3-Propylene Adipate) is manufactured under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent hydroxyl value, acid value, viscosity, and molecular weight distribution meet precise specifications. Certificates of Analysis (COA) documenting these parameters are available upon request to support your quality assurance protocols.

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). Keep the container tightly sealed when not in use to prevent moisture absorption, which can affect product performance.
