Corona Films Incorporated is a leading manufacturer of capacitor grade mica paper. A wide variety of controlled test procedures and over 30 years of experience provide customers with the best mica paper at the lowest possible price. We specialize in thin sheets from ½ mill to 3 mills and any thickness between.
Mica is used in our capacitor paper because of its outstanding electrical and
thermal properties. Our mica paper starts out as 100% muscovite mica. After
cleaning, the mica goes through a special manufacturing process to insure proper
flake size and pulp consistency.
