Custom G10 FR4 G11 Epoxy Fiberglass Rods Bars Machined:
Epoxy Glass Fabric Laminated Rod is made from glass cloth fabric impregnated with epoxy resin, then heated into prepreg and rolling into the rod shape, finally put into the different diameters molds, under high temperature and pressure to cure into the rigid laminated rods.
Epoxy fiberglass rods have extremely high mechanical strength and dimensional stability over temperature, low water absorption, and superior electrical properties when both wet and dry. These electrical properties make it the most widely used in the electrical field. FR4 G-10’s properties are exhibited over a wide range of temperatures and humidities. G-10/FR-4 is available in sheet, rod, and tube for all applications.
Glass Epoxy Laminate - G10 is composed of a woven glass fabric combined with a halogen-free epoxy resin system. The product also offers superior physical properties and excellent electrical characteristics that are maintained in high-humidity conditions. In addition, it is not flame retardant and meets NEMA G-10 requirements.FR-4 is a fire retardant grade of G-10.Also FR-4 is a less expensive option than G10 while also being flame retardant.
