GLASS EPOXY (G10/FR4)
Glass Epoxy, commonly identified as G10 or FR4, is one of the most widely used electrical insulation materials due to its high dielectric strength, dimensional stability, and flame-resistant properties. It is manufactured from woven fiberglass cloth impregnated with epoxy resin, creating a rigid, high-strength laminate suitable for electrical switchgear, busbar supports, transformer insulation, motor slot wedges, and terminal boards. At Hason Industries, Glass Epoxy is machined into precision insulating spacers, standoff pillars, mounting plates, arc barriers, coil supports, and PCB-based mechanical components. Its resistance to moisture absorption makes it ideal for humid or chemically-cleaned production environments, including pharmaceutical manufacturing zones where frequent sanitation cycles are conducted.
We stock Glass Epoxy sheets ranging from 3 mm to 50 mm thickness and machine components up to 1,800 mm × 1,200 mm. Using advanced CNC milling and routing equipment, we achieve tight tolerances, intricate geometries, and smooth surface edges without compromising structural integrity. Because the material contains fiberglass, specialized tooling strategies are used to reduce delamination and edge fraying — an area of expertise our technicians are well trained in.
Glass Epoxy offers excellent tensile and flexural strength, enabling it to support mechanical load-bearing functions in electrical distribution equipment. Its flame retardancy (FR4 grade) ensures safe performance under arc fault conditions. In pharmaceutical equipment, Glass Epoxy is used in control enclosures, automation fixtures, and sensor mounting assemblies where non-conductive stability is crucial to process safety.
Every component undergoes dimensional verification, edge finishing, and burr removal. We document batch traceability and maintain ISO-driven processes to guarantee consistency. Hason Industries offers rapid prototyping for new switchgear layouts and replacement component services for legacy machinery. With its superior thermal endurance and dielectric properties, Glass Epoxy remains one of the most essential insulating materials in modern industrial facilities.
