Take pearlescent pigments as an example, pearlescent pigments are a class of pigments with pearl luster, which are deposited on the substrate (generally natural mica, synthetic mica, glass sheet and other sheet-like materials) above a layer or alternately deposited multiple layers of metal oxides or non-metallic oxides and formed a flat sandwich body with a structure similar to sandwich. Due to the difference in refractive index between the substrate and the oxide deposited on its surface and each oxide, when the light shines on the surface of the pearlescent pigment, the incident light will be refracted and reflected at the interface of each layer of the pearlescent pigment, and the color of the pearlescent pigment that people see is the result of the superposition of light after multiple refractions and reflections of the light, that is, the interference phenomenon of light.

Moreover, the growing trend toward clean beauty products makes mica-based pigments an attractive choice for companies aiming to align with consumer values. However, it is also essential to ensure that mica is sourced responsibly, as unethical practices in mining have raised concerns about human rights in certain regions.

Moreover, the mica industry has been marred by ethical concerns, particularly concerning child labor. Mica is often mined in developing countries where labor laws may be inadequately enforced. Reports of children working in dangerous conditions to extract mica for very low wages have raised significant concerns among consumers and advocacy groups. Companies must ensure that their supply chains are free from child labor and exploitation, promoting ethical sourcing practices that respect workers' rights.

Understanding Non-Metallic Mica Powder Applications and Benefits

Later, with the development of science and technology, people gradually realized that mica minerals have high insulation, high temperature resistance, strong acid and alkali resistance, and mica also began to enter building materials, fire, plastics, paper, rubber, pearlite pigments and other industries. These are mainly Muscovite and phlogopite.

2. Automotive Coatings In the automotive industry, mica-based pigments are utilized to create eye-catching exterior finishes. Car manufacturers often incorporate these pigments into paint formulations to achieve glossy, pearlescent effects that enhance the vehicle's visual appeal. The depth and richness of color provided by mica pigments give cars a sophisticated and luxurious feel that appeals to consumers.
