Cogetherm® Mica plates for high-performance thermal and electrical insulation. Cogetherm is a mica laminate designed for electromechanical and thermomechanical applications. Cogetherm is made in two standard types: Cogetherm M (Muscovite) & Cogetherm P (Phlogopite) Cogetherm M, consists of +/-90% Cogemica Muscovite and +/-10% of bonding material. Cogetherm M has the highest resistance to pressure and is most recommended for complicated cut pieces. For continuous service temperature with temperatue up to 500° C (932° F), we recommend Cogetherm M. Cogetherm P, consists of +/-90%Cogemica-Phlogopite and +/-10% of bonding material. The resistance to pressure of Cogetherm P is less than M and it should be applied only for continous applications > 500° C (932°F) Both Cogetherm M & Cogetherm P are also available in a “desmoked” grade which emits reduced fumes during it’s first applicaction. These grades are known as MC & PC. Standard Plate Size (untrimmed): 40″ x 48″ – which can be cut down to 20″ x 24″ sheets for shipping Thin Gauge Muscovite 505 & Muscovite 132 as well as Phlogopite 505 & Phlogopite 132 Sheets are produced in 39.27″ x 23.62″ & 47.24″ x 39.29″ Sheets.
