Methoxy polyethylene glycol

Application Fields

Construction Materials Industry (Core Application):

Raw material for polycarboxylate superplasticizers: Reacts with acrylic acid to generate MPEG acrylate, used in concrete superplasticizers to improve dispersibility, water reduction rate (>30%), and durability; widely applied in engineering projects such as high-speed railways and bridges.

Reinforcing agents: Improve the dispersibility of cement particles, reduce water consumption, and increase concrete strength (C60 and above).

Pharmaceuticals and Biomedicine:

Drug Delivery Systems:

PEGylation technology: Conjugated with drug molecules via hydroxyl groups (e.g., PEGylated interferon, PEGylated paclitaxel) to prolong the drug's circulation time in the body and reduce toxic side effects.

PROTAC linker: Used as a linker for Proteolysis Targeting Chimeras for cancer treatment.

Biomaterials: Copolymerized with polycaprolactone (PCL) to prepare degradable scaffolds for tissue engineering.

Cosmetics and Personal Care:

Humectants and thickeners: Low molecular weight products (e.g., MPEG 350) are used in lotions and toothpaste; high molecular weight products (e.g., MPEG 5000) are used in lipsticks and foundations.

Mild and non-irritating: Complies with cosmetic raw material safety standards and is suitable for sensitive skin care.

Surfactants and Textile Auxiliaries:

Non-ionic surfactants: Prepared through ethoxylation reactions, used in detergents and emulsifiers; HLB value is adjustable.

Textile printing and dyeing auxiliaries: Improve fabric wettability and enhance dye dispersibility.

Environmental Protection Field:

Biodegradable materials: Copolymerized with biodegradable polyesters (e.g., PLA) to prepare environmentally friendly packaging materials.

Green synthesis solvents: Used as reaction media to replace traditional organic solvents, reducing pollution.
