The adaptability of modified plastics also lies in their ability to be engineered for specific functionalities. For example, certain modified plastics can be made to be fire-retardant, UV resistant, or even antimicrobial, broadening their applicability across various fields including medical devices, consumer products, and construction materials.

X represents large interlayer cations, such as K+, Na+, Ca2+, Ba2+, Rb+, Cs+, etc. Y represents octahedral cations, such as Al3+, Fe2+, Mg2+, Cr3+, Ti4+, Fe3+, etc. Z is mainly Si4+ and Al3+; The ideal ratio of the additional anion (OH)- to (O)2- is 2:10, and (OH)- can be replaced by F- and Cl-. Most mica contain 4% to 5% water. Therefore, although they may be called mica, the chemical composition of different mica may be very different, for the purpose of research, we collectively refer to the minerals with this type of characteristics as mica group minerals.  

The mica variety that does not contain iron is colorless in flakes, and the higher the iron content, the darker the color, and the more polychromatic and absorbable it is. According to the different chemical composition and optical characteristics, mica group minerals can be divided into Muscovite subgroup, biotite-phlogopite subgroup and lemica subgroup. The common mica are biotite, phlogopite, Muscovite and so on.

Natural mica powder and synthetic mica powder also have great differences in electrical insulation, mechanical properties, chemical stability, application range and cost. Natural mica powder has good electrical insulation, but the volume resistivity is lower than that of synthetic mica. Synthetic mica powder has better electrical insulation properties, high volume resistivity and stable dielectric constant, and is suitable for high performance electrical insulation materials. The hardness of natural mica powder is relatively low (2-3), and it has good elasticity and peeling property. The hardness of synthetic mica powder is higher (between 3 and 4), and the tensile strength and compressive strength are better than that of natural mica powder. Natural mica powder is stable in acid-base solution, but it is easy to decompose at high temperature. Synthetic mica powder is stable to acid and base at room temperature, but will be slowly corroded by sulfuric acid above 300℃. Better thermal stability, not easy to release gas. Natural mica powder is widely used in electrical appliances, welding rods, rubber, plastics, paper making, paint and other fields. Synthetic mica powder is mainly used in high-end electrical insulation materials, aviation, aerospace, national defense industry and other high-tech fields. Because synthetic mica powder needs to be produced through complex chemical processes, its production cost is usually higher than that of natural mica powder. Therefore, in the market, the price of synthetic mica powder is often higher than that of natural mica powder. However, with the continuous progress of production technology and the gradual emergence of scale effects, the price of synthetic mica powder is expected to gradually decrease.

Mica powder is generally considered safe for use in cosmetic applications, including lip products. The Cosmetic Ingredient Review (CIR) has assessed the safety of mica and determined that it is safe for use in cosmetics when properly processed. However, there are a few essential points to consider

An authoritative voice in the mica manufacturing sector conveys reliability. Leading manufacturers often participate in research initiatives and industry forums, sharing insights that drive the sector forward. This not only includes developments in product quality but also encompasses sustainable mining and processing practices. The drive towards eco-friendly operations is gaining momentum, with top manufacturers reducing environmental footprints through responsible sourcing and waste-reduction techniques. Their commitment to sustainability speaks to a greater trustworthiness, aligning with global consumer priorities.

As sustainability becomes increasingly important to consumers, many brands are now exploring eco-friendly alternatives to traditional pearlescent pigments. Natural mica and plant-derived pigments are gaining traction, offering environmentally conscious choices without compromising quality. These formulations can appeal to a demographic that prioritizes ethical products, blending aesthetics with social responsibility.
