Commutator Mica Paper

the best quality of muscovite, phlogopite or synthetic mica

Uncalcined Mica paper is made by hydraulic separation process using the best quality of muscovite, phlogopite or synthetic mica ,which is first reduced to pulp and then made into the form of paper in rolls. It mainly used for all kind of mica sheets and mica tapes. Width: 900-1040mm.Inside diameter of paper spool: 76-152mm,Packing: In wooden case with contents wrapped up in plastic film
