Use

Methylene chloride is used principally as a solvent in paint removers. It is also used as an aerosol propellant, processing solvent in the manufacture of steroids, antibiotics, vitamins, and tablet coatings; as a degreasing agent; in electronics manufacturing; and as a urethane foamblowing agent.Methylene chloride is also used in metal cleaning, as a solvent in the production of polycarbonate resins and triacetate fibers, in film processing, ininkformulations, and as anextraction solvent for spice oleoresins, caffeine, and hops. It was once registered for use in the United States as an insecticide for commodity fumigation of strawberries, citrus fruits, and a variety of grains.
