Description

Polyhexamethylene Oxide is a high-purity, linear polyether glycol with a defined molecular weight range. This versatile chemical intermediate is valued for its excellent hydrophilicity, flexibility, and compatibility in demanding formulations. It is essential for manufacturers in the polyurethane, specialty polymer, and pharmaceutical industries seeking consistent performance and reliable supply. The compound is also known by its CAS number 31762-63-7.

Application

• Polyurethane Elastomers & Coatings: As a soft segment polyol for producing high-performance, flexible, and hydrophilic polyurethane materials.
• Pharmaceutical Excipients: Used in controlled-release drug delivery systems and as a solubilizing agent.
• Specialty Polymer Synthesis: A key monomer or macromonomer for creating block copolymers, surfactants, and dispersants.
• Lubricants & Functional Fluids: Serves as a base fluid or additive in synthetic lubricants due to its thermal stability and low pour point.
• Adhesives & Sealants: Imparts flexibility and moisture resistance in advanced adhesive formulations.
• Surface Active Agents: Utilized in the production of non-ionic surfactants and emulsifiers.

Quality Control

Our Polyhexamethylene Oxide is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including determination of hydroxyl value, molecular weight distribution, water content, and color. Certificates of Analysis (COA) documenting purity and key specifications are provided to ensure it meets the rigorous standards required for industrial and pharmaceutical applications.

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 absorption of atmospheric moisture, which can affect product quality.
