G-10/FR4

G-10/FR4

This glass/epoxy laminate offers a superior strength/size ratio in addition to its self-extinguishing properties. In addition to its high mechanical strength, it exhibits good dielectric loss and electrical strength under a range of dry and humid conditions. The flame resistance is Class I in accordance with NEMA test method 7.11. Read our G-10 Guide.

A History of G-10 and FR-4

G-10 is a thermosetting industrial laminated plastic consisting of a woven glass cloth material and an epoxy resin matrix. First introduced in the 1950’s, G-10 was the original glass of epoxy laminate used in printed circuitry. The high strength, excellent electrical properties, and chemical resistance of G-10 make for a very versatile material that is now being used in a wide variety of applications.

Today most of what is called G-10 is actually FR-4, the flame retardant version of G-10. This explains why you will also see the material designated G-10FR. This means FR-4. The material FR-4 can usually be used where G-10 is called out, however, G-10 should not be used where FR-4 is specified.

    FAQs

    Current manufactures NEMA grade G-10/FR4 products. These materials can be fabricated into tubes, rods, and sheets. They can also be machined into spacers, standoffs, and other parts. We can also design one specific to you based on your unique applications. Whatever your manufacturing or assembling needs, there’s a Current Inc. product that will improve your product for an affordable price. Our laminated sheets, standoffs, tubing, rod and spacers are created with precision in mind. 

    G-10 is a thermosetting industrial laminated plastic consisting of a woven glass cloth material and an epoxy resin matrix. The “G” stands for glass epoxy and the “10” denotes specific properties of this type of glass epoxy. Standard G-10 is not fire retardant, but today most of what is called G-10 is actually FR-4. FR-4 is G-10 with fire retardant properties that can be used in electrical applications, whereas standard G-10 cannot.

    We offer paper laminates in natural and black. Canvas and linen are available in a variety of colors such as black, blue, and red. Our G-10/FR4 laminates are available in various grays, reds, black, blue, browns, white, greens, purple, pink, orange, yellow, glow in the dark, and even camo. We also manufacture combinations of colors in marbling and burl upon request. Examples of these can be found on the What’s New Page
