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.

1. Improved Mechanical Properties Mica powder is renowned for its ability to improve the tensile strength and durability of soft plastics. When integrated into plastic formulations, mica enhances resistance to wear and tear, helping products withstand everyday use. This property is especially important in the manufacturing of soft plastic items that require flexibility and resilience.

하지만 주의할 점도 존재합니다. 미카 파우더는 온도에 민감하게 반응할 수 있는데, 너무 높은 온도에서 사용할 경우 그 색상이 변하거나, 기본적인 물성을 잃을 수 있습니다. 따라서, 왁스를 녹일 때의 온도는 낮춰주고, 미카 파우더를 넣을 때는 비교적 낮은 온도가 아닐 때 추가하는 것이 좋습니다. 일반적으로 왁스가 약 60도에서 70도 정도 일 때 추가하면 가장 이상적입니다.
