✦ Synopsis
E. I. du Pont de Nemours and Company has announced a new plastic electrical insulation which will not support combustion. Designated "Rulan" flame-retardant plastic, the new material will not burn after the flame has been removed, and neither will it drip when molten. Its power factor, over a wide range of frequencies, is 0.002, its dielectric constant is 2.7. It can be extruded on to wire at high speeds, and can also be injection molded.
