FR-4 (or FR4) is a NEMA grade designation for glass-reinforced epoxy laminate material. FR-4 is a composite material composed of woven fiberglass cloth with an epoxy resin binder that is flame resistant (self-extinguishing).
"FR" stands for flame retardant, and denotes that the material complies with the standard UL94-0. 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.
Characteristics & Applications:
3240, 3240-1&3240-3, EPGC201 and G10:Primarily intended for mechanical,electrical, electronic usual applications, with high strength under moderate temperature and good electrical properties under high humidity; 3240-1&3240-3 are derived type from 3240, with lower properties, and lower price, it is economical type product of 3240; EPGC201 and G10 have better electrical property than 3240.
