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 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.

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.

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.
