Description

Trimethylolpropane Ethoxylate is a versatile polyol ether derivative, synthesized by the ethoxylation of trimethylolpropane. This compound serves as a crucial reactive intermediate and performance additive, valued for its trifunctional hydroxyl groups and hydrophilic polyether chain. It is essential for manufacturers in the coatings, adhesives, and polymer industries seeking to enhance product flexibility, hydrophilicity, and cross-linking density.

Application

• Polyurethane Systems: A key polyol component for flexible foams, elastomers, and coatings, imparting improved resilience and hydrolytic stability.
• Radiation-Curable Resins: Used as a reactive diluent and oligomer in UV/EB-curable inks, coatings, and adhesives.
• Synthetic Lubricants: Acts as a base fluid or additive to improve viscosity index and thermal-oxidative stability.
• Polyester & Alkyd Resins: Incorporated to modify resin properties, enhancing flexibility and water resistance.
• Personal Care & Cosmetics: Functions as a humectant, emollient, and carrier in various formulations.
• Chemical Intermediate: Serves as a building block for further chemical synthesis, such as surfactants and specialty esters.

Quality Control

Our Trimethylolpropane Ethoxylate is manufactured under a stringent quality management system. Every batch undergoes comprehensive analytical testing to ensure consistency and compliance with agreed specifications. A Certificate of Analysis (COA) detailing key parameters such as hydroxyl value, water content, and degree of ethoxylation is provided with each shipment to guarantee traceability and product integrity.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be kept under a dry inert atmosphere (e.g., nitrogen) after opening to prevent moisture absorption and oxidation. Keep away from strong oxidizers.
