FR4 G10 Epoxy Fiber Glass Parts

HONY®FR4 is a NEMA grade designation for glass-reinforced epoxy laminate material. FR-4 is a composite material composed of woven fiber cloth with an epoxy resin binder that is flame resistant (self-extinguishing).

"FR" stands for "flame retardant", and does not denote that the material complies with the standard UL94V-0 unless testing is performed to UL 94, Vertical Flame testing in Section 8 at a compliant lab. The designation FR-4 was created by NEMA in 1968.

FR-4 glass epoxy is a popular and versatile high-pressure thermoset plastic laminate grade with good strength to weight ratios. With near zero water absorption, FR-4 is most commonly used as an electrical insulator possessing considerable mechanical strength. The material is known to retain its high mechanical values and electrical insulating qualities in both dry and humid conditions. These attributes, along with good fabrication characteristics, lend utility to this grade for a wide variety of electrical and mechanical applications.

Grade designations for glass epoxy laminates are: G-10 ,G-11, FR-4, FR-5 and FR-6. Of these, FR-4 is the grade most widely in use today. G-10, the predecessor to FR-4, lacks FR-4's self-extinguishing flammability characteristics. Hence, FR-4 has replaced G-10 in most applications.

FR-4 epoxy resin systems typically employ bromine, a halogen, to facilitate flame-resistant properties in FR-4 glass epoxy laminates. Some applications where thermal destruction of the material is a desirable trait will still use G-10 non flame resistant.

G10 FR4 glass epoxy laminate Description:

FR4 G10 Glass Epoxy Cutting Board is specified for its extremely high strength and high dimensional stability over temperature. G-11 is used for terminal boards, high humidity applications, electrical and electronic test equipment and electric rotor insulation. G-11 is difficult to cut or machine and may require special equipment.

G-10 is slightly Stronger while G-11 is a better insulator and can withstand higher temperature G-11 and similar fibreglass reinforced thermosets are sometimes known as Garolite.

HONY Plastic is an industry leader in FR4 and G10 machining. We are able to maintain tolerances, create features and produce parts that even the material manufacturers deem unobtainable. By using high speed spindles capable of turning at 30,000 RPM, tightly controlled work envelopes and cutting edge work holding systems, HONY Plastic can machine components from the most simple part to the most intricate part on any of the 35 machines in our facility.
