    Electrically Insulating Mica Sheets

    Image of Product. Front orientation. Mica. Electrically Insulating Mica Sheets.
    Insulate electrical components in everything from toasters to circuit breakers. These sheets provide greater vibration resistance than ceramic and withstand higher temperatures than plastic. They can operate continuously at temperatures up to 930° F, but if they stay above that temperature for too long, they may turn to carbon and stop insulating. These sheets meet UL 94 V-0 for flame retardance. Also known as muscovite mica.
    Semi-Rigid—These sheets bend like a playing card, so they provide some spring power. Cut them with scissors, punches, or die stamps.
    Rigid—Machine with high-speed steel or tungsten carbide tools.

    Flexible Electrically Insulating Mica Sheets

    A resin binder gives these sheets enough flexibility to be used as wrap-around electrical or thermal insulation. They operate continuously at temperatures up to 930° F, but if they stay above that temperature for too long, they may turn to carbon and stop insulating. They meet UL 94 V-0 for flame retardance. Cut these sheets with scissors, die stamps, or punches. Also known as muscovite mica.

    Nonflammable Mica Panels

    Image of Product. Front orientation. Mica. Nonflammable Mica Panels.
    Designed to withstand the punishing heat of jet engines, these panels retain their strength for hours even when exposed to hot gas flames. Tested to EN 13501-1 Class A1, they meet the strictest non-combustibility requirements. Use them as a lightweight alternative to carbon fiber, plastic, or aluminum to make fire-rated enclosures, electrical housings, and structural panels. They can be machined with standard cutting and milling tools. All ship with a traceable lot number printed on the packaging.

    Electrically Insulating Mica Tubes

    Image of Product. Front orientation. Mica. Electrically Insulating Mica Tubes.
    Insulate electrical components in environments exposed to high heat. These tubes are often used to support wire leads in electric vehicle batteries. They provide greater vibration resistance than ceramic and withstand higher temperatures than plastic. They can operate continuously at temperatures up to 930° F, but if they stay above that temperature for too long, they may turn to carbon and stop insulating. Also known as muscovite mica.
    Rigid—Saw, score, or cut to length with standard tools.
    Wall Thickness—The thicker the wall, the better a tube can withstand high voltages, resist crushing, and hold up to heat cycling. Thinner walls allow for some heat transfer and are easier to cut.
