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.
|Application||Terminal boards, knife handles, jigs and fixtures, engine mountings|
|Advantages||Insulating, fire resistant, low maintenance, high strength-to-weight ratio, moisture resistant, dimensionally stable|
|Disdvantages||Properties break down under prolonged exposure to UV light|
|Lead Time||Lead time is generally a minimum of 3 days. However, this can increase depending on complexity and manufacturing origin.|
|Tolerances||Machining tolerances of 0.005” (0.13mm) are achievable.|
|Wall Thickness||A minimum wall thickness of 0.03” (0.8mm) is achievable. This can vary depending on the ratio of wall thickness to planar dimension.|
|Max Part Size||The maximum size of the part is determined by the machines available and the complexity of the part.|
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.
|Tensile Strength, Yield (MPa)||Compressive Strength (MPa)||Hardness (Rockwell M)||Flammability Rating||Glass Transition Temperature (oC)|
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.
