Custom mica rings and discs are often used as high-temperature electrical insulators (for example, in heater elements, transformers, or sight windows). These parts are typically stamped or machined from mica sheets. The most common mica types are muscovite (white or “ruby” mica) and phlogopite (amber/green mica). Muscovite has the highest diele

Mica is a plate-like mineral valued for its excellent electrical and thermal insulation. In industrial use, it comes as flexible tapes or rigid sheets/plates. Each form uses similar mica materials but differs in construction and use. Below, we compare mica tape and rigid mica sheet in terms of composition, insulating properties, form factor, applic

Industrial processes in power generation, chemical plants, metal refining, and automotive systems often involve flanged joints that must stay leak-free at extreme temperatures. A mica gasket is literally a “high-temperature and chemically resistant sealant” made from mica sheets, used to prevent leaks. Mica is a naturally heat-resistant mineral
