Glass / Silicone (G-7)
This glass-silicone laminate has excellent dielectric loss properties under dry conditions and good electrical properties under humid conditions. It also has excellent heat and arc resistance and is self-extinguishing. It is often used for electrical grade insulation as well as heating and appliance insulation.
While silicones do not retain their strength as well as epoxies and phenolics over time under lower temperatures, they are stronger over time under high heat conditions (over 400 degrees F).
