Glass-Epoxy (G-10, FR-4, G-11)
Epoxy resins are widely used in electronic applications because they are virtually impervious to moisture. Glass epoxy has outstanding mechanical and electric strength as well as good dielectric properties.
FR-4 is a fire-retardant grade of G-10 while the G-11 grade offers improved mechanical strength at higher temperatures. Epoxy resins are a good choice for many electrical and mechanical applications.
