G10-Fr4 Sheets

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-Fr4 Rod

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.

G10-FR4 Tube

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.

Cryogenic G10

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.


G10 FR4 laminate grades are produced by inserting continuous glass woven fabric impregnated with an epoxy resin binder while forming the sheet under high pressure. This material is used extensively in the electronics industry because its water absorption is extremely minimal and the G10 line of materials is not electrically conductive. The G10 FR4 is most commonly used in PCB (Printed Circuit Boards) applications. G10 exhibits superior mechanical and dimensional stability and doesn't shrink. Temperature ratings of 180 degrees C. In addition to these properties, G10/FR4 has excellent dielectric loss properties, and great electrical strength.The difference between Grades G10 and FR4 is that FR4 is a fire retardant grade of G10. FR4 (also known as Garolite) can be substituted where G10 is specified; G10 can never be substituted for FR4. G10 is also known as Micarta and Garolite and can be used for structural supports, buss bars, mechanical insulation, gears, test fixtures, washers, spacers and tight tolerance machined parts for electromechanical assemblies.
