High-temperature electrical insulation calls for woven glass fabric laminates (SRBGF), which keep their dielectric strength and resistance to surface tracking at elevated temperatures. For the highest temperatures, the Tufnol range includes the silicone glass grade 10G/50 and the polyimide glass grade 6G/92, while the epoxy glass grades combine high strength with good electrical insulation. Check the rated temperature limit for each grade on the Tufnol working temperatures guide.
