4. Durability Once embedded in resin, mica flakes become part of the durable structure, ensuring that their beauty lasts. Unlike paint or other surface treatments that might wear over time, mica flakes retain their luster.

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.

Having surveyed the market dynamics, it's evident that successful mica exporters possess a profound understanding of both resource acquisition and supply chain management. These exporters strategically source high-quality mica from prominent mining regions to ensure a consistent supply. By cultivating relationships with reputable mines, they can procure mica that adheres to strict quality control measures, thereby satisfying international standards. This expertise ensures that the mica provided has optimal performance characteristics required by end-users.

In short, there are significant differences between natural mica powder and synthetic mica powder in production methods, color and appearance, performance characteristics, application fields, and price and cost. Synthetic mica powder is superior to natural mica powder in terms of high temperature resistance, transparency, electrical insulation, stability and mechanical properties, while natural mica powder has more advantages in resource acquisition, cost and color. When choosing which type of mica powder to use, you can consider the high temperature resistance of the required material, electrical insulation performance, transparency and color requirements, evaluate the mechanical strength and hardness of the required material, consider chemical stability and other different application scenarios and technical requirements to make a reasonable choice.

2. Customization Mica powder comes in various colors and particle sizes, allowing for extensive customization. Artists can mix different shades to create a unique palette, enabling them to achieve specific artistic visions. This versatility also means that mica powder can be used in combination with various types of paint, including acrylics, oils, and watercolors.
