Polypropylene Glycol (PPG)

  • Description

Description

Polypropylene Glycol PPG are polymers of propylene oxide. Polypropylene Glycol PPG is vastly employed in production of a wide range of products, including such diverse. Commodities as polyester resins, engine coolants, latex paints, heat transfer fluids, and deicing compounds. It is used as a solvent, heat transfer medium, or as a chemical intermediate, taking. The benefit of its reactive hydroxyl groups. Polypropylene Glycol PPG is a polypropylene glycol used as a used in production of brake Fluid formulations, lubricating-oil and grease compounding and rubber processing. PPG is less toxic as compared to PEG, so biotechnologicals are now switching from PEG to PPG.
