    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.
