Tufflam Glass Epoxy Laminate Sheet NEMA G11 FR5 is a thermosetting industrial fibre 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 a very high operating temperature, 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 G11 was the designation given to Glass Epoxy sheet composite by the National Electrical Manufacture Association (NEMA) to specify a consistent product between manufactures.It certifies to NEMA G11 FR5 and MIL-I-24768/28.
Glass Epoxy Laminate Sheet Nema G11 laminate sheet is made up with a hight temperature epoxy making up the bulk of heavy sheet and then using finer glass cloth with high temperature resistant epoxy giving a high performance outer finish.
Today what is called FR5 is the Brominated flame retardant version of G 11. The FR 5 material can usually be used where G11 material is specified, however G11 Laminate should not be used where FR-5 is specified.
Another variation of G11 fiberglass sheet is G11 CR laminate used in cryogenic applications.
Both G-11 and FR-5 are rated at 155 degree C continuous operating temperature.G11 has a low dielectric loss and has a retention of 50% of mechanical properties at 155 C. Because of these characteristics, this material should be used in applications where temperatures in excess of 130 degrees C are encountered. Because they are thermosets, no melting will occur with these grades, however charring will be observed after extended periods above this temperature rating. FR-5 has a UL flammability rating of 94 V-0.
Glass Epoxy Laminate Sheet - NEMA G11 has Anti-fire properties and is easily machined and Die Cut. We are able to custom machine and cut sheets to your specifications.
