Mica, like talc, is a sheet silicate with an excellent platelet structure. The most important grades of mica are muscovite and phlogopite. Both these grades have aspect ratios of 20–40 and are used in thermoplastics to improve rigidity, dimensional stability, and HDT. Mica also exhibits good electrical properties and is acid resistant [52 ...
Micas are a group of silicate minerals, primarily known for their platy nature. Muscovite and phlogopite are two of the most common forms of mica. Phlogopite mica has a distinct reddish brown color and is more flexible the muscovite mica. Muscovite mica is white and is more brittle than phlogopite mica. Main uses for mica: Plastic Reinforcement.
