What are Mica Pigments?

Construction Industry: Resin mica powder is incorporated into paints and coatings to enhance durability and add a decorative finish to surfaces.

Types of Pigment Powders

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.

Huajing mica cosmetic grade mica powder has been loved by customers since it entered the market, and has a general response, excellent quality, stable quality and high reputation.

Moreover, matte mica powder generally poses little risk for skin irritation, making it suitable for sensitive skin types. However, as with any cosmetic ingredient, it’s pertinent to choose high-quality formulations that minimize the risk of allergic reactions. Always conducting a patch test before fully integrating new products into your beauty routine can help ensure compatibility with your skin type.

Natural high quality Muscovite:feel fine, soft lubrication.

During the processing, pay attention to fire and explosion prevention to ensure the safety of the production environment.

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.

Thus, China's role in the mica industry is characterized by its strategic integration of cutting-edge technology, dedication to sustainability, and adherence to global standards. These factors collectively convey a robust image of reliability, expertise, and authority, ensuring that Chinese mica remains a cornerstone in the development of next-generation products across the globe.

Understanding Mica Flakes

For example, the safe operation of high-speed rail cannot be separated from the escort of mica products.

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.
