Polyethylene glycol monobutyl ether

Core Application Areas

Industrial Solvents and Cleaning Agents

Coatings and Inks: Used as a high-boiling solvent for dissolving nitrocellulose and synthetic resins, improving film leveling and drying speed.

Electronics Cleaning: BPEG500/BPEG750 can effectively remove flux residues from circuit board surfaces, meeting the requirements of the precision electronics industry for low ionic residues.

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: BPEG1000 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 Personal Care

Detergents: Used as a solubilizer in laundry detergents to enhance oil stain dispersion capability, with excellent biodegradability.

Skin Care: High molecular weight BPEG (e.g., BPEG2000) can serve as a humectant, adjusting paste consistency and improving skin feel.

Specialized Fields

Automotive Brake Fluid: BPEG750, due to its high boiling point (>320°C) and low freezing point (<-40°C), is a key component of DOT4 brake fluid.

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