G10 FR4 is a thermosetting industrial fiber glass composite laminate consisting of a continuous filament glass cloth material with an epoxy resin binder. This product, first introduced in the 1950's, has characteristics of high strength, low moisture absorption, excellent electrical properties and chemical resistance. These properties are maintained not only at room temperature but also under humid or moist conditions. NEMA G10 was the designation given to Glass Epoxy sheet composite by the National Electrical Manufacture Association (NEMA) to specify a consistent product between manufactures.
In today's G10 laminate sheet is made up with epoxy making up the bulk of heavy sheet and then using finer glass cloth with high temperature resistant tetra-functional epoxy giving a high performance outer finish.
Today what is called G10 composite is actually FR4, the Brominated flame retardant version of G 10. The FR 4 material can usually be used where G10 material is specified, however G10 Laminate should not be used where FR-4 is specified.
Another variation of G10 fiberglass sheet is G10 CR laminate used in cryogenic applications.
Both G-10 and FR-4 are rated at 285 degree F continuous operating temperature. Because they are thermosets, no melting will occur with these grades, however charring will be observed after extended periods above this temperature rating. FR-4 has a UL flammability rating of 94 V-0.
FR4 is for MEMA standard, accordance with the international IEC standard :EPGC202.
G10 is for MEMA standard, accordance with the international IEC standard :EPGC201.
