Description

Ethylene Glycol Bis(Propylene Glycol-B-Ethylene Glycol) Ether is a high-purity, multi-functional polyglycol ether with a defined block copolymer structure. This specialized chemical is valued for its excellent solvency, coupling, and humectant properties, making it a versatile performance additive. It is primarily sought after by formulators in the polymer, coatings, and personal care industries for its ability to modify rheology and enhance product stability.

Application

• Polymer Industry: Used as a reactive diluent, viscosity modifier, and processing aid in polyurethane and epoxy resin formulations.
• Coatings & Inks: Acts as a coalescing agent and solvent in water-based and solvent-based systems to improve film formation and flow.
• Personal Care: Functions as a humectant and emollient in cosmetic and skincare products, helping to retain moisture.
• Chemical Intermediates: Serves as a building block for the synthesis of more complex surfactants and specialty esters.
• Industrial Cleaners: Employed as a coupling agent in degreasers and cleaning formulations for its solvency power.
• Textile Processing: Utilized as a lubricant and softening agent in fiber treatment and dyeing processes.

Quality Control

Our Ethylene Glycol Bis(Propylene Glycol-B-Ethylene Glycol) Ether is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, hydroxyl value, and water content are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after initial use to prevent moisture absorption, which can affect product quality.
