Silicon Glass Cloth Laminated Sheet (SiGC, NEMA G7) is made of
several layers of glass cloth impregnated with silicon resin by
processing under heat and pressure, the natural color is typically
cream to white which has excellent heat and arc resistance. It can
be used as a slot insulation in high temperature motor, arc
clapboard in the switch and so on.
