IEC standard is subdivided into EPGC 201, EPGC 202, EPGC 203, EPGC 204, EPGC 306, EPGC308, etc. NEMA (National Electrical Industry of the United States) standards are divided into G10, FR-4, G11 and FR-5, etc.
Introduction of EPGC202/FR-4:
Epoxy glass fiber cloth laminate sheet is a hard plate insulation material made of alkali free glass fiber cloth soaked in epoxy resin by hot pressing. IEC standard is subdivided into EPGC 201, EPGC 202, EPGC 203, EPGC 204, EPGC 306, EPGC308, etc. NEMA (National Electrical Industry of the United States) standards are divided into G10, FR-4, G11 and FR-5, etc.
EPGC202/FR-4 epoxy sheet have the following characteristics: good electrical performance in high humidity environment, good mechanical performance at medium temperature, voltage resistance, flame retardant (FR series) and stable product quality, etc. It can be processed into various parts and components by means of lathe processing, stamping, trimming, drilling, sandblasting, grinding, saw and milling.
Epoxy fiberglass laminate sheet is widely used in motor, electrical equipment, circuit breakers, switch cabinets, transformers, DC motors, AC contactors, explosion-proof appliances, star wheel, low-voltage electrical insulation baffles, etc., electrical, electronic, automotive industry and other fields.
