Silicone coated fiberglass braided sleeving is used for insulation of leads and connections in electrical and electronic components ( transformers, coils, relays, solenoids etc.) where temperature range from –70°C through 200°C are encountered. Silicone rubber coated glass sleeving is the only flexible insulating material which remains useful for continuous service in ambient temperatures from -70°C through +200°C. Operation at temperatures up to 315 ° C is tolerated for short durations. Exceeds all requirements of UL Subject 224 for 200 ° C, 600-volt operation. It also exceeds the requirements of MIL-I-3190, MIL-P-18057, and ASTM D372.
