About Mica Insulating Washers

Mica Insulating Washers Product Overview Mica Insulating Washers are precision-cut electrical insulation components made from natural mica sheets (typically Muscovite or Phlogopite) or mica paper bonded with resins. These washers are designed to provide excellent thermal and electrical insulation in high-temperature and high-voltage environments. Key Features: High dielectric strength (1020 kV/mm) Exceptional heat resistance (up to 1000C for phlogopite mica) Moisture and chemical resistance Good mechanical stability Can be CNC-machined, punched, or die-cut Typical Specifications: PropertyValue / RangeMaterialMuscovite / Phlogopite Mica, or Mica Paper with Silicone/Epoxy BinderOuter Diameter (OD)5 mm 100 mm+Inner Diameter (ID)2 mm 50 mm+Thickness0.2 mm 3 mm+Temperature ResistanceUp to 500C (Muscovite), 1000C (Phlogopite)Dielectric Strength 15 kV/mmColorSilver-Grey, Gold, Brown, Natural Common Applications: IndustryUse CaseElectrical & ElectronicsInsulating spacers in terminals, switchgearPower ToolsThermal barrier for heating elementsAutomotive & EVBattery insulation, thermal washersAerospaceFireproof insulation between fastenersAppliancesUsed in irons, toasters, and induction devices Why Use Mica Washers Instead of Plastic/Fiber?
