 Grade G-7 sheet is constructed from a continuous filament woven glass fabnc. with a silicone resin binder The resin system is flame retardant and arc resistant. G7 sheets extremely good dielectne loss properties under dry conditions and good electrical properbes under numid conditions, although the percentage of change from dry to humid condiDons is high. Excellent flame
heaL and arc resistance. Meets UL 94. Class VO,flame resistance.
