Description

Trimethylolpropane Ethoxylate is a versatile polyol ether surfactant derived from the ethoxylation of trimethylolpropane. This compound is valued for its excellent hydrophilicity, reactivity, and ability to function as a building block for more complex polymers and surfactants. It is essential for manufacturers in the polyurethane, coatings, and specialty chemical industries seeking to modify product flexibility, solubility, and cross-linking density.

Application

• Polyurethane Industry: A key polyol component for producing flexible foams, elastomers, and coatings, imparting improved hydrophilicity and mechanical properties.
• Surface Coatings & Resins: Used as a reactive diluent and cross-linking agent in alkyd, polyester, and radiation-curable resins to enhance film flexibility and adhesion.
• Surfactant & Emulsifier Synthesis: Serves as a hydrophilic intermediate for manufacturing non-ionic surfactants and emulsifiers used in agrochemicals and textile processing.
• Lubricant & Hydraulic Fluid Additives: Employed as a base fluid or additive to improve the viscosity index, thermal stability, and water solubility of synthetic lubricants.
• Adhesives and Sealants: Functions as a plasticizer and modifier to adjust the viscosity and cure profile of various adhesive formulations.
• Personal Care Products: Utilized in the synthesis of emollients and conditioning agents for creams, lotions, and hair care products.

Quality Control

Our Trimethylolpropane Ethoxylate is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistency and compliance with agreed specifications. Key parameters such as hydroxyl value, degree of ethoxylation, water content, and color are monitored. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee traceability and quality assurance for our global B2B clients.

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) and should be kept under an inert atmosphere (e.g., nitrogen) after opening to prevent moisture absorption and oxidation. Keep away from strong oxidizing agents.
