Functions and Applications:

        MPEG350 is mainly used as a solvent for oils, nitrocellulose, synthetic resins, alcohol-soluble dyes, and ethyl cellulose. In the coatings industry, it serves as a quick-drying agent for varnishes and a coating thinner.

MPEG500 is primarily used in the printing and dyeing industry as a penetrating agent and leveling agent, as an additive in the fuel industry, as a dyeing auxiliary in the textile industry, and as an organic synthesis intermediate for pharmaceuticals and pesticides. It is particularly suitable for zero-VOC environmentally friendly solvent systems.

MPEG750 is used as a cleaning agent for electronic chemicals, as well as a solvent for coatings, printing inks, stamp pad inks, oils, and resins. It is also used in metal cleaners, paint strippers, lubricant removers, automotive engine cleaners, dry cleaning solvents, epoxy resin solvents, and pharmaceutical extraction agents. Additionally, it serves as a stabilizer for latex paints, an evaporation inhibitor for aircraft coatings, and a surface finishing improver for high-temperature baked enamels.

MPEG1000 is mainly used as a high-boiling-point solvent for inks, dyes, resins, cellulose, and coatings. When added to coatings, it improves flow, brushability, and leveling. It can also be used as a hydrocarbon extraction agent and as an intermediate in the preparation of ester derivatives in organic synthesis.

MPEG1200 is mainly used in automotive brake fluids, chemical reagents in analytical chemistry, and organic synthesis intermediates for pharmaceuticals and pesticides. It is also used in brake fluids and as a raw material for organic synthesis. It is particularly suitable as a monomer raw material for ester-type polycarboxylate superplasticizers.

Note: Special specifications such as MPEG1250, MPEG1500, and MPEG2000 can be customized upon request.
