Developing concurrently with the early Mica days, it was on December 20, 1939, that Russell Robinson led a National Advisory Committee for Aeronautics (NASA) work crew in turning the first shovel of dirt on the corner of Moffett Field that would become the NACA Ames Aeronautical Laboratory. The objective was space travel, and the need for precision control of magnetic fields began to emerge. Perfection Mica Company created a Division charged with developing them.
Also under development in the late 1940s, Television created a new industry and a demand for minimizing/eliminating magnetic field influence on vacuum tubes and other electronic components. Specifically, control of magnetic interference on Cathode Ray Tubes (CRT) - the heart of Televisions.
The awareness of Perfection Mica in the electronics industry led an easy transition to the Division's involvement in aerospace, medical, television, telephone, radio, appliance and pure research.
It became apparent after several years of pursuing one opportunity after another that the fledgling Perfection Mica Company needed to re-invent itself. Designing and producing shields for magnetic interference was the solution settled upon, and by the mid 1940s, both Mica products and magnetic shields were being produced in their factory on North Elston Avenue in Chicago.
By the mid-1950s, magnetic shields overtook the Mica business, and Magnetic Shield Corporation officially became the primary enterprise in 1956. By this time, Glenn's son, James, had entered the business and was instrumental in developing and implementing marketing materials.
An early trademark, "Magna-Shield", had been coined in the 1940s to differentiate their proprietary shielding materials. Specifications were on record at the Navy, Army, RCA, Raytheon and a number of university research institutes calling for "Magna-Shield" magnetic shielding materials.
Then fate intervened. When James applied to the U.S. Patent and Trademark Office in the early 1950s for trademark protection of "Magna-Shield", it was denied! Undaunted, the Powers family revisited the naming process, and the trademarks of Netic® and Co-Netic AA® were born. Both were successfully registered in 1955.
To this day, Netic and Co-Netic AA are recognized worldwide as the benchmark in magnetic shielding alloys.
