The lifetime, reliability and functionality of rotating electric machines are fundamentally impacted by the quality of their insulation systems. This aligns perfectly with the excellent properties of natural mica.

COGEBI draws from longstanding experience with the processing of natural mica and produces mica paper of all common grades and types in world-class quality. The high-end mica papers COGEMICA® and REMIKA®, constitute the key components of insulating materials produced for resin-rich as well as VPI insulation technologies.
