Technology

Fiberglass is perfected by Owens-Illinois and Corning Glass Works. Made of fine glass filaments, it can be spun into yarn and woven into fabrics or used as insulating material.

Teflon (Fluon) is discovered accidentally by Ohio-born Du Pont chemist Roy J. (Joseph) Plunkett, 28, while working on refrigerants. An excellent electrical insulation material, the polytetrafluoroethylene plastic is stable over a wide range of temperatures and resistant to most corrosive agents. It will be marketed under the name Fluon by Britain's Imperial Chemical Industries and find many industrial uses.
