Light Green Glass Epoxy Sheet / G10 Fr4 Sheet Excellent Heat Resistance
Light green FR4 epoxy sheet / Light green EPGC202 with high mechanical strength
Product Introduction:
Light green FR4 epoxy sheet is a rigid insulating lamination sheet made of composed imported alkali-free glass fiber cloth ,impregnated with imported high quality epoxy resin,added the imported fire retardant and cementing compound,it is a rigid plate-like insulating material under high temperature and high pressure.
Light green FR4 epoxy sheet are widely used in every kinds of switch cubicle such as burshing disk,arc extinguishing chamber ,arcing cylinger,arcing piece,flash barrier,wiring board,terminal plate insulating support;stru parts and bus-bar supports in switchear & transformer, the armature parts of electrical machine such as cover plate,slote wedge,stator ,gasket,shims,carbon brush etc,the epoxy glass laminated sheet series are used much more extensively in consumer electronics.panels display and photovotaic in recent years.
