Caption

Teflon research. Laboratory technician testing a piece of Teflon (polytetrafluoroethylene, PTFE), a DuPont industrial plastic. She is placing the sample in an instrument which measures its dielectric constant and power factor when an electric current is applied. Because its dielectric loss factor is extremely low, Teflon is an excellent insulating material for currents of ultra-high frequency. It is used in radar and television equipment. Teflon was discovered in 1938 by DuPont researchers. Photographed at the DuPont site in Richmond, Virginia, USA, in around the 1940s.
