Laytex, an Unusual Dielectric, Is Announced. Announcement has been made by the United States Rubber Company of a new type of electrical insulation, called Laytex, which possesses a number of unusual qualities. Its principal application so far has been as a covering for wires, and it is believed by the manufacturer that its superior properties will require in time that all existing codes and specifications on wire insulation will have to be rewritten. It is claimed that of all known flexible insulation, Laytex is the most flexible, has the highest tensile strength and resistance to compression, and has the highest dielectric strength and insulation resistance. Because of these qualities, it permits thinner but superior walls which in turn make possible finished conductors lighter in weight and smaller in bulk. In certain applications, a reduction of 25 per cent in the outside diameter, and 50 per cent in the weight of the conductor are effected.
