· Abstract. Mica (i.e., muscovite and phlogopit) are platelet-shaped reinforcing fillers used for increasing heat deflection temperature and reducing warpage in polymers. Mineralogically the mica group consists of phyllosilicates all with monoclinic crystal structure and perfect basal cleavage. Micas are muscovite (typically white to gray

Mica. Mica is a mineral name given to a group of minerals that are physically and chemically similar. They are all silicate minerals, known as sheet silicates because they form in distinct layers. Micas are fairly light and relatively soft, and the sheets and flakes of mica are flexible. Mica is heat-resistant and does not conduct electricity.
