Polypropylene glycol methyl ether

Core Application Areas

Industrial Solvents and Cleaning Agents

Coatings and Inks: MPPG-400 serves as a high-boiling solvent for dissolving nitrocellulose and synthetic resins, improving film leveling and drying speed; MPPG-600 acts as a zero-VOC eco-friendly solvent for water-based coating systems, lowering film-forming temperature and promoting film formation.

Electronics Cleaning: MPPG-800 effectively removes flux residues from circuit board surfaces, meeting the low ionic residue requirements of the precision electronics industry, and is also used in semiconductor wafer cleaning agents.

Metalworking: Used as a coupling agent in cutting fluids to enhance the affinity between lubricants and metal surfaces, reducing wear.

Polymer Material Synthesis

Polycarboxylate Superplasticizers: MPPG-1000 is copolymerized with acrylic acid to produce high-performance superplasticizers; a dosage of 1.0% achieves a water reduction rate of over 30%, widely used in high-speed rail and nuclear power projects.

Polyurethane Raw Materials: Used as a chain extender or crosslinking agent to improve the flexibility and water resistance of polyurethane elastomers.

Daily Chemicals and Pharmaceuticals

Personal Care: High molecular weight MPPG (e.g., MPPG-2000) acts as a humectant, adjusting paste consistency and enhancing the skin feel of skincare products.

Pharmaceutical Carriers: Used as a drug solubilizer to improve the bioavailability of poorly soluble drugs (e.g., paclitaxel) for tablet and capsule formulations.

Specialized Fields

Automotive Brake Fluid: MPPG-800, due to its high boiling point (>320°C) and low freezing point (<-40°C), is a key component of DOT4 brake fluid.

New Energy Batteries: Used as an electrolyte additive to enhance the stability and cycle life of lithium batteries, with related demand growth projected to reach 18-20% by 2025.
