Description

α-Hydro-ω-Hydroxy-Poly(Oxy-1,2-Ethanediyl) Polymer With 1,6-Diisocyanatohexane, Polyethylene Glycol Mono[(1-Phenylethyl)Phenyl] Ether-Blocked is a specialized, non-ionic polyurethane-based surfactant and polymer additive. This compound is engineered to provide excellent surface activity, foam control, and compatibility in complex formulations. It is primarily utilized by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in advanced polymer processing, where it acts as a stabilizer, dispersant, or rheology modifier.

Application

• Polyurethane Foam Stabilizer: Acts as a cell opener and foam stabilizer in flexible polyurethane foam production, improving breathability and physical properties.
• Coatings & Inks Additive: Used as a dispersing agent and flow control additive in solvent-based and high-solid coatings, printing inks, and varnishes to enhance leveling and prevent defects.
• Adhesive & Sealant Formulation: Serves as a rheology modifier and compatibility agent in polyurethane and hybrid adhesive/sealant systems, improving application properties and final bond strength.
• Elastomer Processing Aid: Incorporated into thermoplastic polyurethanes (TPU) and other elastomers to aid in processing, reduce internal friction, and improve surface finish.
• Industrial Surfactant: Functions as a non-ionic surfactant for demanding applications requiring stability in the presence of strong alkalis and organic solvents.
• Polymer Modification: Used as a macromonomer or chain extender/blocker to tailor the properties of polyether-based polyurethanes, influencing hydrophilicity and flexibility.

Quality Control

Our production of this advanced polymer adheres to strict quality management systems. Each batch is characterized for critical parameters including hydroxyl value, isocyanate content (NCO%), viscosity, and molecular weight distribution to ensure consistent performance in your formulations. Comprehensive Certificates of Analysis (COA) detailing assay, identity, and physical specifications are provided with every shipment.

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/59-77°F). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from strong alkalis and incompatible organic solvents.
