A New Molded Insulator.
So many new insulating materials have been recently introduced claiming heat-resisting qualities that to the uninitiated there would seem to be little room for improvement along these lines. To users, however, it is well known that while there are a number of excellent heat-proof materials on the market there are few which have been sufficiently developed beyond the experimental stage to insure uniform and continuous production.
It is, therefore, of interest to learn that Emile Hemming, chemist of the Hemming Manufacturing Company, and the inventor of its well-known "Gummon" and "Hemit" molded insulating materials, has, after a long series of experiments and careful tests, succeeded in producing a new material which, it is claimed, possesses great dielectric and tensile strength and all of the elasticity and resiliency of the older forms of shellac compounds, which it is designed to replace owing to its heat-resisting qualities. "Tegit," as this new material has been named, its makers claim, is not affected by temperatures up to 600 degrees Fahrenheit, and is absolutely waterproof, not warping or cracking when subjected to climatic changes.
It is further claimed for "Tegit" that is has been successfully produced for some time and is being placed on the market only after the manufacturing process has been perfected to a point insuring a standard reliable product.
While "Tegit" is designed to meet conditions for which "Gummon" or "Hemit" may not be entirely suited, it will not replace these materials for the many purposes for which their preminent characteristics make them desirable.
The Hemming Manufacturing Company, of Garfield, New Jersey, are the manufacturers of this new product.
