【Performance and Application】
1. This product is a non-ionic surfactant, easily soluble in water, ethanol and organic solvents, with low vapor pressure and thermal stability.
2. MPEG-200 has a very low freezing point and can be added to various oils as an antifreeze.
3. MPEG-350~1500 is widely used in cosmetics, skin care products, and pharmaceutical industries as a base and viscosity modifier for creams, ointments, and sticks, and can play a role in thickening.
4. MPEG-1000~2000 reacts with acrylic acid or methacrylic acid to prepare MPEG (meth)acrylate, which is the main macromonomer for the production of polycarboxylate high-efficiency cement water reducing agent.
