一．Product Property
Polyethylene glycol monomethyl ether (MPEG) is a non-ionic surfactant. It appears as a colorless to pale yellow liquid or a paste-like solid. This product has excellent water solubility and chemical stability. The methoxy and hydroxyl groups at the molecular ends give it excellent reactivity. MPEG is low in toxicity and non-irritating, meeting the safety standards of the pharmaceutical and cosmetic industries. It also has multiple functional characteristics such as wetting, emulsification, and dispersion. Depending on the molecular weight specifications, it can be widely used in fields such as drug carriers, coating additives, and textile auxiliaries, meeting the needs of various applications ranging from solvents to thickeners.
二．Quality Index
| Grade | Appearance (25°C) | Hydroxyl Value (mgKOH/g) | Molecular Weight | Moisture (%) | pH Value |
| MPEG-600 | Viscous liquid | 88-100 | 560-640 | ≤0.5 | 5.0-7.0 |
| MPEG-750 | Viscous liquid | 70-80 | 700-800 | ≤0.5 | 5.0-7.0 |
| MPEG-1000 | Waxy paste | 47-56 | 1000-1200 | ≤0.5 | 5.0-7.0 |
| MPEG-2000 | White solid | 25.5-31 | 1800-2200 | ≤0.5 | 5.0-7.0 |
三．Application scope and Usage
It is used in the building materials industry as a raw material for reducing water content in cement and enhancing its properties. The polycarboxylic high-efficiency type water reducer synthesized with this raw material has strong ability to disperse cement particles and maintain dispersion. As a result, the product has the advantages of low dosage, high water reduction rate, good reinforcing effect, good durability, resistance to corrosion of reinforcing bars, and environmental friendliness. It can be applied in high-performance and high-strength (above C60) commercial concrete for on-site mixing and long-distance transportation.
Soluble in water, ethanol and organic solvents. Low vapor pressure, stable to heat. Used as a thickener and lubricant in the textile printing and dyeing industry as well as in the cosmetics industry.
