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 for 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.

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

Synthesis of Polymer Materials

Polycarboxylate Superplasticizers: BPPG-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. For example, in polypeptide film modification, BPPG-1000 significantly enhances film flexibility.

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, adjusting paste consistency and improving skin feel.

Specialized 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: Used as an electrolyte additive to improve the stability and cycle life of lithium batteries, with related demand growth expected to reach 18-20% by 2025.
