| Rigid mica material for heating equipment |
The rigid mica plate for heating equipment is made by
selected mica material mixed with proper adhesive
after pressed and baked. It has good machanical
strength and property of heat resistance. The quality
is stable and reliable and its characteristics have
reached or partially surpassed the international
standard (IEC or UL). main technical characteristics.
