Garolite G-10 is a glass-reinforced epoxy composite with a high strength-to-weight ratio, and excellent corrosion and moisture resistance, making it ideal for marine applications. It is also fire-resistant and a great electrical insulator, making it a material of choice for electronic circuit board substrates.
Garolite G-10 is a thermoset composite made from fiberglass and phenolic epoxy resin. As a thermoset, G-10 cannot be melted and reformed. If it is heated above its peak operating temperature it breaks down chemically and will not retain its properties once cooled. This makes injection molding in garolite impossible. CNC machining in Garolite G-10 is the only method of manufacturing complex parts with this material.
CNC machining in Garolite G-10 produces parts that are ideal for corrosive or high-moisture applications. Typically, these combinations of environmental conditions are found in the marine industry where G-10 is used for engine components such as mounting brackets as well as for applications that require electrical insulation and mechanical strength.

Garolite G-10 is typically a yellow/green material but is also sold in black. It does not take well to polishing due to its fibrous composition. Typically, polishing its matte surface finish will not buff out to a shine.
Garolite G-10 is a high-cost engineering plastic and as such, it is important to limit manufacturing costs where possible.
