Super-capacitor special-purpose FR4 epoxy sheet / EPGC202 sheet specified for new energy
Product Introduction:
Super-capacitor special-purpose 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.
Super-capacitor special-purpose 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.

Super-capacitor special-purpose FR4 epoxy sheet
Super capacitor is a promising field in the energy storage system. Its energy storage principle is the physical reaction, which is similar to the use of lithium batteries, and applies to new energy vehicles, new energy buses and so on.
Most of insulating material used in supercapacitor's fixed installation, according to the using conditions require fire report, flame retardant grade meet V-0, heat resistance at least meet F grade, firm installation ,with basic of electrical properties. The commonly materials used are HC-GPO3/HC-FR4 etc.
