Description

Hexanedioic Acid, Polymer With 1,3-Butanediol, Hexadecanoate is a specialized polyester polyol derived from adipic acid, 1,3-butanediol, and hexadecanoic acid. This engineered polymer is valued for its role as a versatile building block, offering tunable properties for high-performance material synthesis. It is primarily required by formulators and manufacturers in the polymer and coatings industries seeking to develop products with specific flexibility, hydrophobicity, and durability characteristics. CAS No. 68332-62-7.

Application

• Polyurethane Elastomers & Foams: Serves as a key polyol component for producing flexible and rigid foams, as well as elastomers with enhanced mechanical properties and hydrolytic stability.
• Specialty Coatings & Adhesives: Used in the formulation of high-performance polyurethane coatings, sealants, and adhesives, contributing to improved weatherability, adhesion, and chemical resistance.
• Resin Modification: Acts as a modifier for alkyd, polyester, and other resins to impart flexibility, reduce viscosity, and alter surface characteristics.
• Plasticizers & Additives: Functions as a polymeric plasticizer or compatibilizer in PVC and other polymer systems to improve processing and end-product performance.
• Lubricants & Greases: Employed in the synthesis of ester-based synthetic lubricants and thickeners for high-temperature applications.
• Biomedical & Controlled Release: Potential use in creating biodegradable polymers for medical devices or drug delivery matrices, owing to its tailored degradation profile.

Quality Control

Our production of Hexanedioic Acid, Polymer With 1,3-Butanediol, Hexadecanoate adheres to stringent quality management protocols. Each batch is characterized for critical parameters including hydroxyl value, acid value, viscosity, and molecular weight distribution to ensure batch-to-batch consistency and performance reliability. Certificates of Analysis (COA) documenting these specifications are available upon request, supporting your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent moisture absorption, which can affect product properties. Keep away from strong oxidizers, acids, and bases.
