Atlas Fibre carries a range of glass epoxy composite materials, including G-10, an industrial laminated plastic. G-10 is the older sibling of FR-4, another type of glass epoxy. Learn more about the properties, applications, and benefits of G-10 glass epoxy.
G-10 consists of woven fiberglass and an epoxy resin binder. Originally used in printed circuits, it was introduced in the 1950s and was the first glass epoxy laminate. G-10 sheets have excellent electrical properties and chemical resistance. They also have high strength, making the material very versatile.
Variations of G-10 are often ideal for use in cryogenic applications because of the material’s ability to withstand subzero temperatures. Some versions of G-10 are also flame retardant.
G-10 has high dielectric, tensile, and flexural strength. It’s chemically resistant and can resist thermal shock. Notable G-10 plastic properties include the following:

G-10 has a low shearing strength, which allows for higher feeds and speeds during fabrication. Less rake and greater clearances are required of the cutting tools, but it can otherwise be worked using standard machine tooling.
G-10 is closely related to FR-4 glass epoxy. FR-4 is G-10 with the addition of being flame retardant. While similar, the two materials aren’t exactly interchangeable. If your application calls for G-10, it’s often acceptable to use FR-4 in its place. However, if your application calls for FR-4, you can’t use G-10 as a substitute.
There are several notable advantages of using G-10 in certain applications. Among the material’s benefits are:
G-10 can have an incredibly long life depending on where and how it is used. While exposure to sunlight can shorten its life span, it’s virtually permanent when used on the interior of machines.
G-10 is available in tubes, sheets, and rods and in a range of colors to fit specific needs. It’s appropriate for various applications, including uses in the medical industry. Since it has excellent electrical properties, it’s frequently used as insulation.
Examples of uses for G-10 include:
