属性

主要特点与优势

Low Volatility: High boiling point and low vapor pressure minimize evaporative loss and lower VOC emissions in industrial processes.
Superior Solvency: Effectively dissolves a diverse range of resins, oils, and greases, ensuring clear and stable formulations.
Excellent Coupling Efficiency: Acts as a powerful co-solvent, promoting the miscibility of water with insoluble organic components.
Thermal and Chemical Stability: Maintains structural integrity in both acidic and mildly alkaline environments and resists thermal degradation.
Wetting and Leveling: Enhances the penetration and spreadability of liquids on various substrates by significantly reducing surface tension.
Improved Safety Profile: Exhibits lower toxicity and reduced skin permeability compared to E-series glycol ethers with shorter alkyl chains.

技术亮点

Chemical Formula: C₄H₉(OCH₂CH₂)_nOH (where n typically represents 3 or more ethylene oxide units).
Physical Appearance: Clear, colorless to pale yellow liquid with a faint, characteristic ethereal odor.
Boiling Point: Typically exceeds 230° C (446° F), depending on the degree of ethoxylation.
Flash Point: High flash point (generally >120° C), reducing flammability risks during storage and high-temperature processing.
Solubility: Completely miscible in water and a wide spectrum of organic solvents, including alcohols, ketones, and aliphatic hydrocarbons.
Specific Gravity: Ranges between 0.985 and 1.020 at 20° C.
Viscosity: Low to moderate kinematic viscosity, providing excellent fluid lubricity in hydraulic applications.
