Fiber glass reinforcements help meet the transportation industry’s high performance and durability demands. Under the hood, fiber glass reinforces air intake manifolds, and on the surface it provides lightweight strength, chemical resistance and durability to automotive bumpers. PPG is a key transportation-industry supplier of windshields, windows and cockpit glass; automotive paints and protective coatings; and silicas used in tires – in fact, PPG products may cover more than 90 percent of the visible part of a vehicle.
