Mica Sheet come in two mineral types of mica, Muscovite and Phlogopite. We can deliver both in rigid or flexible sheets, depending on what you intend to use them for. The standard size is 1000 x 1200mm or 1000 x 2400mm. Typically, mica’s plate-like form lends itself to superior insulation and electrical and chemical resistance. These properties are especially useful when using mica in sheet form as a durable reinforcing agent.
