Polypropylene glycol monobutyl ether

Core Application Areas

Industrial Solvents and Cleaning Agents

Coatings and Inks: As a high-boiling solvent, used for dissolving nitrocellulose and synthetic resins, improving the flow and leveling of paint films and drying speed. For example, BPPG-500 can serve as an active solvent in solvent-based coatings to enhance resin solubility.

Electronics Cleaning: BPPG-750 effectively removes flux residues from circuit board surfaces, meeting the requirements of the precision electronics industry for low ionic residues.

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

Polymer Material Synthesis

Polycarboxylate Superplasticizers: BPPG-1000 is copolymerized with acrylic acid to produce high-performance superplasticizers; a dosage of 1.0% can achieve 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. For example, in polypeptide film modification, BPPG-1000 can significantly enhance the flexibility of the film.

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 BPPG (such as BPPG-2000) can serve as a humectant, regulating the consistency of creams and improving skin feel.

Special Fields

Automotive Brake Fluid: Due to its high boiling point (>320°C) and low freezing point (<-40°C), BPPG-750 is a key component of DOT4 brake fluid.

New Energy Batteries: As an electrolyte additive, it improves the stability and cycle life of lithium batteries, with demand in this sector expected to grow by 18-20% in 2025.
