Cold Flexible Splittings Plate

We specialize in the manufacture of simple and complex Mica parts, and have a design and engineering team capable of supporting product development, change and fulfillment. Our production capabilities are further elevated by proprietary and internally developed equipment that push fabrication options beyond the scope of other fabricated mica parts manufacturers. Building our Mica Splitting products in-house at our Virginia Facility gives us a significant advantage in controlling the quality of the product, review process with the clients and then allows very low lead times.

Cold flexible mica splittings plate produced to NEMA 6 and NEMA 86 standards. NEMA 6 is bonded with Polyester resin and NEMA 86 with a Silicone resin. Applications include dry type transformer phase insulation, coil wrappers and slot liners. Sheet size of 36" x 36" or 18" x 36" or in strips. Thickness tolerances of +/- .003" average, + .008"/-.005" individual for thickness range of .010" - .020". Thickness tolerance of +/- .005" average, and +.010"/-.008" individual for thickness range of .020" - .060".
