Magnetic Shield

Magnetic Shield Corporation, a division of Perfection Mica Company, is the premier supplier of custom magnetic shields, room and wall EMF shields and magnetic shielding material.

The Perfection Mica Company was born in 1941 to meet the demand for electronic component insulation, that increased dramatically during World War II. The Magnetic Shield Division was created in the late 1940's, again to meet customer demand for this new technology. The awareness of Perfection Mica in the electronics industry helped the Division's entry into aerospace, medical, television, telephone, radio, appliance and pure research.

By the mid-1950s, magnetic shields overtook the Mica business, and Magnetic Shield Corporation officially became the primary enterprise. In 1955 trademark status was granted for the two alloys that are the benchmark of magnetic shielding materials - NETIC® and CO-NETIC®.
