About GPO-3|Glass-polyester laminate. A thermoset laminate with good electrical insulation properties, arc resistance, and flame retardancy. Less expensive than G-10/FR-4. Used for electrical switchgear, bus bar supports, and transformer components. Machines with carbide due to glass fiber abrasiveness. Creates fiberglass dust, so use extraction. Compare to G-10/FR-4 (stronger, better mechanical properties) and Phenolic Grade XX (different base resin, similar applications).
About Plate|Thick flat stock, generally 3/16" and up, used for machined base plates, fixture plates, wear surfaces, and structural fabrication. Heavier grades get milled, drilled, and tapped directly.
