    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

    Image of Product. Front orientation. Mica. 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.

    Flexible Ultra-High-Temperature Electrically Insulating Mica Sheets

    Image of Product. Front orientation. Mica. Flexible Ultra-High-Temperature Electrically Insulating Mica Sheets.
    The most heat-resistant mica sheets we offer. Since they can also be shaped without cracking, they’re often used to make gaskets for automotive exhaust manifolds, gas and oil burners, and heat exchangers. A silicone resin binder gives these sheets enough flex to ship in rolls, so you can use a machine to punch out parts with less waste.
    These sheets won’t melt like plastic or break like ceramic, so they can insulate electrical parts exposed to high heat and vibration. They can withstand temperatures up to 2000° F for a few minutes, but if they stay above 1800° F for too long, they may turn to carbon and stop insulating. Also known as phlogopite mica.
