Description

Hexanedioic Acid, Polymer With 1,3-Butanediol And 1,4-Butanediol is a specialized aliphatic polyester polyol, also known as a poly(butylene adipate) derivative. This engineered polymer is valued for its role as a versatile building block in the synthesis of high-performance polyurethanes and other specialty polymers. It is essential for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for producers of biodegradable and bio-based materials seeking specific mechanical and degradation properties.

Application

• Polyurethane Elastomers: Serves as a key soft segment polyol for producing flexible, durable elastomers with good hydrolysis resistance.
• Coatings & Adhesives: Used in formulating solvent-borne and high-solids coatings, as well as adhesives, providing excellent flexibility and adhesion.
• Biodegradable Polymers: A fundamental component in the production of compostable and bio-based polyesters for packaging and agricultural films.
• Thermoplastic Polyurethanes (TPU): Imparts low-temperature flexibility and resilience in TPUs for automotive, footwear, and industrial applications.
• Sealants & Caulks: Contributes to the elasticity and long-term weatherability of construction and industrial sealants.
• Resin Modification: Acts as a polymeric plasticizer or modifier for other resin systems to enhance toughness and impact resistance.

Quality Control

Our production of Hexanedioic Acid, Polymer With 1,3-Butanediol And 1,4-Butanediol adheres to stringent quality management protocols. Each batch is characterized for critical parameters including hydroxyl value, acid value, molecular weight distribution, and viscosity to ensure consistent performance in downstream formulations. Certificates of Analysis (COA) detailing these specifications are provided with every shipment to guarantee traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (15-25°C/59-77°F). Keep the container tightly sealed when not in use to minimize moisture absorption and prevent contamination.
