G10/FR4 sheet is a thermosetting industrial laminate consisting of continous filament glass cloth with an epoxy resin binder.

Grade G10/FR4 laminates sheet is with high mechanical strength at room temperature, good electrical properties under dry and humidity conditions. It is flame retardant.

G10/Fr4 Sheet material is versatile and rigid holding up to high temperatures in tough electrical and high moisture environments.  Using a G10/FR4 board / panel for applications such as: buss bars, terminal boards, insulators, unclad PC boards, bushings and electrical housing units is a great way to ensure minimal design issues.  All of our G10/Fr4 sheet panels are measured and pass strict quality inspection.
