GPO-3 (UPGM203) Sheet

GPO-3, also called UPGM203, is a standard electric insulating material with excellent arc resistance and superior heat resistance.

GPO-3 sheet is a rigid sheet insulation material made of alkali-free glass fiber glass impregnated with unsaturated resin polyester paste and heat pressed with appropriate additives. We can provide non-abrasive sheet and abrasive sheet, and the thickness tolerance of abrasive sheet is more accurate.
