Yaan Catalog Product Information
Composition of the Silicone Impregnating Varnish:
silicone resin, modifier, solvent, drier, etc.
Main advantages of the Silicone Impregnating Varnish:
H-class insulation material. With excellent heat resistance, long-term operating temperature is allowed to be 180 ~ 200 ℃ or higher without significant weight loss.
Good dielectric properties. The dielectric constant, breakdown strength, and volume resistance do not change much at high and low temperatures (-50 to 250 ° C) and a wide frequency range; cold resistance, acid and alkali resistance, radiation resistance, and oxidation resistance.
