Description

Poly(Hexamethylene Carbonate) Diol is a high-purity, aliphatic polycarbonate diol characterized by its well-defined molecular weight and terminal hydroxyl functionality. This compound serves as a critical, high-performance building block for the synthesis of advanced polyurethanes and other specialty polymers. It is essential for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product durability, flexibility, and hydrolytic stability.

Application

• High-Performance Polyurethane Elastomers: Used to impart excellent mechanical properties, low-temperature flexibility, and hydrolysis resistance.
• Waterborne Polyurethane Dispersions (PUDs): A key raw material for eco-friendly coatings and adhesives with superior weatherability.
• Thermoplastic Polyurethanes (TPU): Enhances the processing and final properties of TPUs for films, cables, and automotive parts.
• Specialty Coatings and Sealants: Provides long-term durability, chemical resistance, and adhesion in demanding environments.
• Biomedical and Biocompatible Polymers: Suitable for synthesizing degradable polymers for controlled-release and medical device applications.
• Modifier for Resins and Plastics: Acts as a polymeric plasticizer or compatibilizer to improve toughness and flexibility.

Quality Control

Our Poly(Hexamethylene Carbonate) Diol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistency in hydroxyl value, molecular weight distribution, acid value, and color. Certificates of Analysis (COA) documenting purity and key specifications are available for every shipment 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 under a dry inert atmosphere (e.g., nitrogen) to prevent moisture absorption and potential degradation.
