G10-FR4 (FR4) is a fire rated electrical-grade dielectric made with and epoxy material reinforced with a woven fiberglass mat. FR-4 is an abbreviation for Flame Resistant 4. FR-4 is commonly used in printed circuit boards. FR4 material conforms to the requirements of military specification Mil P 13949 Type F, MIL-S-13949/04 GF/GFN/GFK and Mil I 24768/2 and is rated UL 94V-O. FR4 material is also known as Garolite.
G10 Rod is a continuous woven glass fabric laminated with an epoxy resin. This G10 Rod grade is extremely high in mechanical strength, has low moisture absorption and dissipation factors, and has superior electrical characteristics which are exhibited over a wide range of temperatures and humidities.
Nema Grade G10/FR4 tubing is an electrical-grade epoxy resin system combined with a glass fabric substrate, cast to a specific size and either formed or ground down to the desired specifications. G10 tubes also offer excellent chemical resistance and electrical properties under dry and humid conditions. Grade G-10/FR4 tube is flame retardant and at 300 degrees F retains 25% of its flexural strength while maintaining all of its electrical properties.
IPC GRADE / CRYOGENIC GRADE G10 is an electrical and mechanical grade of glass cloth laminate impregnated and cured with a non-brominated epoxy resin. Also referred to as G10-CR, G10 CR conforms to Mil Spec Mil-I-24768/2 Type GEE . G-10 CR contains no halogens and can be used in nuclear and space applications.
