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.

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

Natural mica powder and synthetic mica powder have differences in production methods, heat resistance and color transparency. As the name suggests, natural mica powder is made from natural mica ore after processing, retaining the original characteristics and composition of the ore. Its main components are SiO2 (about 49%) and Al2O3 (about 30%), while also containing K2O+Na2O (9%-11%) and so on. The synthetic mica powder (such as fluoroglogopicite powder), is the use of a variety of raw materials through high temperature reaction and other chemical methods synthetic, its composition and characteristics can be adjusted and optimized according to the need, the chemical formula is KMg3(AlSi3O10)F2, belongs to the monoclinic crystal system, is a typical layered silicate, relatively single and pure composition. The heat resistance of natural mica powder is generally 500-600℃, and some types, such as phlogopite, can reach 800℃. The heat resistance of synthetic mica powder is more excellent, and it can withstand high temperatures above 1200℃, and the melting point or crystallization temperature is about 1375±5. The transparency of natural mica powder is relatively low, and the color is diverse, including black, yellow, white, gray, green, brown and other colors, and may vary due to different ore types and processing methods. The color of synthetic mica powder is relatively single, usually colorless transparent or white, high whiteness, good optical performance, and high transmittance from ultraviolet to infrared band.

Muscovite, commonly known as white mica, is the most abundant type of mica. Its name is derived from its historical association with the Muscovy glass, an early form of glass containing a high amount of silica. Muscovite is characterized by its transparency and excellent cleavage, allowing it to be split into thin sheets. These sheets are lightweight and can easily be used as insulators in electrical applications, as they can withstand high temperatures. Additionally, muscovite is often used in the cosmetic industry, where it's prized for its shimmering quality in products such as eyeshadows and highlighters. The optical qualities of muscovite also make it suitable for use in windows in high-temperature furnaces.

Understanding Mica

2. Versatile Shades and Textures Glitter mica powder is available in a wide array of colors, allowing for endless customization options in lip gloss formulations. Whether you desire a soft, muted hue or a bold, vibrant shade, there’s a glitter mica powder to match your vision. The texture of mica also provides a silky feel, ensuring that the lip gloss glides smoothly on the lips.

Mica flakes are characterized by their unique physical and chemical properties

As consumers are becoming increasingly environmentally conscious, the demand for sustainable and natural ingredients in cosmetics is on the rise. Mica, being a natural mineral, is often sourced ethically, especially when companies prioritize fair-trade practices. This focus on sustainable sourcing allows consumers to indulge in beauty products that are not only beneficial for their skin but also considerate of the planet.

In conclusion, mica powder is a valuable additive for soft plastics, providing an array of benefits that enhance both aesthetic and functional aspects of the final products. From improving thermal stability and durability to introducing unique visual effects, mica serves as a versatile material that meets the diverse needs of various industries. As innovation continues to evolve, the application of mica powder in soft plastics promises to play a pivotal role in shaping the future of product design and manufacturing. Ultimately, its blend of performance and beauty makes mica powder an essential ingredient for anyone looking to elevate their soft plastic products.
