Cogemica® Range of Porous Mica Tapes for VPI

The Cogemica®-VPI tape is manufactured from muscovite mica paper Cogemica.
 
 A paper with high porosity laminated on one side to a support which gives strength, and the other (optional, depending on type) to a protective layer that prevents the release of the mica particles during wrapping all linked by a small amount of specially formulated epoxy resin.
 
 During manufacture, the volatile content enjoyable 0.5% of total weight is reduced, achieving a dry, flexible, highly absorbent and compatible with all types of tape impregnating resins VPI.
 
 The Cogemica®-VPI accelerant tapes are compatible with most impregnation resins employed today. The properties of the full insulation systems depend heavily on the quality of the impregnating resin used in the VPI process.
 
 The Cogemica tapes along with the impregnating resin for VPI ULTIMEG 2002 HV form a tested insulation system, high-quality, long-term durability and performance.
