Long known as the OEM of Mykroy/Mycalex machinable and moldable glass bonded mica ceramics, Crystex Composites LLC is embarking on a new business venture by producing and selling "off the shelf" stand off insulators to be sold under the trade name MYCALEX® Insulators...

The first of these insulators the MM50 (50mm diameter and 50mm tall) & MM35 (35mm diameter and 35mm tall) are now available. Other sizes will be released during the 3rd and 4th quarters of 2009.

This product line will target the transportation (railway) industry and the alternative energy market. Some typical applications are:


  • Railway motors
  • Resistor boxes
  • Heater system
  • Switchbox mountings
  • Insulation supports for HF windings
  • Mountings for trolleys
  • Overhead switch controls
  • High temperature terminals
  • Arc separators
  • Switchgear chambers
  • And many others…

Produced using Crystex' proprietary formulae and molding processes, these insulators will share the same advantages as the other Mykroy/Mycalex glass bonded mica ceramics produced by Crystex:

  • Completely inorganic – does not burn
  • High dielectric strength & arc resistance
  • Low thermal conductivity: Between 1-1.5 W/mk
  • Withstands thermal cycling
  • Impervious to moisture, oils, and gases
  • Can be machined: drilled, tapped or threaded with carbide tools
  • Ability to be silicone or Teflon coated.
  • Inert to solvents, oxygen plasma and weak acids & bases.
  • Operating temperatures: –175°C to 400°C depending on grade
  • Accepts metal inserts: Nickel alloys, Copper, Brass, SS, Molybdenum
