    Flexible Extra-High-Temperature Electrically Insulating Mica Sheets

    Image of Product. Front orientation. Mica. Flexible Extra-High-Temperature Electrically Insulating Mica Sheets.
    A silicone resin binder gives these sheets enough flexibility to be used as wrap-around electrical or thermal insulation. They're often used on electric vehicle batteries as liners and sleeving, or as gaskets in spots where plastics would melt from extreme heat. These sheets can withstand temperatures up to 1800° F for a few minutes, but if they stay above 1275° F for too long, they may turn to carbon and stop insulating. They meet UL 94 V-0 for flame retardance. Also known as phlogopite mica. Cut these sheets with scissors, die stamps, or punches.

    Extra-High-Temperature Electrically Insulating Mica Sheets

    Line furnaces in steel mills or cover components in aerospace engine bays. These sheets maintain electrical insulating properties and strength under extreme heat. They dissipate heat slowly and predictably for precise temperature control. Because they’re abrasion resistant, they’re ideal for extreme material handling components, such as the parts that guide blown glassware pieces as they leave red-hot molds. These sheets can withstand temperatures up to 1800° F for a few minutes, but if they stay above 1275° F for too long, they may turn to carbon and stop insulating. They meet UL 94 V-0 for flame retardance. Also known as phlogopite 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.

    Extra High-Temperature Easy-Machine Glass-Mica Ceramic Sheets and Bars

    Also known as Macor, this glass-mica ceramic withstands temperatures up to 1470° F. You can machine complicated shapes and precision parts from it in a fraction of the time it would take using other types of fired ceramic. Its good electrical and thermal resistance make it a common choice for heating and soldering fixtures.

    Extra High-Temperature Easy-Machine Glass-Mica Ceramic Rods

    Image of Product. Front orientation. Ceramic. Extra High-Temperature Easy-Machine Glass-Mica Ceramic Rods.
    Also known as Macor, this glass-mica ceramic withstands temperatures up to 1470° F. You can machine complicated shapes and precision parts from it in a fraction of the time it would take using other types of fired ceramic. Its good electrical and thermal resistance make it a common choice for heating and soldering fixtures.

    Extra-High-Temperature Electrically Insulating Mica Tubes

    Image of Product. Front orientation. Mica. Extra-High-Temperature Electrically Insulating Mica Tubes.
    Shield electrical parts in extremely hot areas, such as kilns and furnaces. These tubes maintain their insulating properties at extreme continuous operating temperatures, and can also withstand flashes of even hotter temperatures. However, if they stay above that temperature for too long, they may turn to carbon and stop insulating. They provide greater vibration resistance than ceramic and withstand higher temperatures than plastic. Also known as phlogopite 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.
