Nema Grade G10/FR4 tubing is an electrical-grade epoxy resin system combined with a glass fabric substrate, cast to a specific size and either formed or ground down to the desired specifications. G10 tubes also offer excellent chemical resistance and electrical properties under dry and humid conditions. Grade G-10/FR4 tube is flame retardant and at 300 degrees F retains 25% of its flexural strength while maintaining all of its electrical properties.
