Mica powder, derived from the finely crushed mineral mica, has gained significant traction in numerous industries due to its unique properties and appealing aesthetics. When combined with epoxy resin, this natural powder transforms into a versatile material that can be utilized in various applications, ranging from art projects to industrial finishes. This article delves into the defining characteristics, benefits, and diverse applications of epoxy mica powder, shedding light on why it has become a popular choice among artisans and manufacturers alike.

It is an indispensable and important raw material in the fields of electric heating equipment, wire and cable, aerospace and so on.

- Ingredient Transparency Reputable suppliers will provide clear information about their mica’s sourcing, processing, and any added ingredients.

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.
