Description

Polydecamethylene Oxide is a high-purity, linear polyether glycol characterized by its well-defined molecular structure and terminal hydroxyl functionality. This compound is valued for its role as a versatile building block and intermediate in advanced polymer synthesis, offering predictable chain length and reactivity. It is essential for manufacturers in the polyurethane, specialty elastomer, and high-performance lubricant industries seeking consistent quality and reliable performance in their formulations.

Application

• As a key monomer or chain extender in the synthesis of segmented polyurethane elastomers and thermoplastic polyurethanes (TPUs).
• As a precursor for specialty lubricants and functional fluids, where its thermal and oxidative stability is advantageous.
• In the production of block copolymers for use in adhesives, coatings, and impact modifiers.
• As a reactive intermediate for creating surface-active agents and functional polymers with tailored properties.
• For research and development of biomedical materials, including biodegradable polymers and drug delivery systems.
• In formulations requiring a hydrophilic polyether segment to modify flexibility, hydrophilicity, or compatibility.

Quality Control

Our Polydecamethylene Oxide is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for molecular weight, hydroxyl value, and purity. Certificates of Analysis (COA) documenting these results are available upon request to support 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 (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to minimize exposure to atmospheric moisture, which can affect product quality.
