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 film leveling and drying speed. For example, BPPG-500 can serve as an active solvent in solvent-based coatings, enhancing 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.

　　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: 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 film flexibility.

　　Daily Chemicals and Personal Care

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

　　Skincare Products: High molecular weight BPPG (such as BPPG-2000) can serve as a humectant, adjusting paste consistency and improving skin feel.

　　Specialized Fields

　　Automotive Brake Fluid: BPPG-750, 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 improve the stability and cycle life of lithium batteries; the demand growth rate in this sector is expected to reach 18-20% by 2025.
