Mica is a very common rock-forming mineral, widely distributed in crystalline rocks. Its general chemical formula can be expressed as:

Another significant benefit of mica powder is its role as a filler that can help reduce production costs. By incorporating mica into plastic formulations, manufacturers can achieve desired physical properties with less reliance on more expensive resins and additives. This cost-effective solution not only lowers material costs but can also streamline the manufacturing process, ultimately increasing profitability.
