The identification of mica powder is very simple. According to years of sales experience, there are roughly the following methods, which are for your reference only: price of synthetic mica powder

First of all, the whiteness of mica powder is not high, about 75; at present, the quality of mica powder on the market is mixed, and it is really difficult to find a better supplier. I often receive questions from customers, and the whiteness of mica powder is about 90. Under normal circumstances, the whiteness of mica powder is generally not high, only about 75. If it is mixed with other fillers such as calcium carbonate, talc, etc., the whiteness will be greatly improved.

Second, the mica powder has a flaky structure. Take a beaker, add 100ml of pure water, and stir with a glass rod. It can be seen that the mica powder has good suspension; other fillers include transparent powder, talcum powder, calcium carbonate and other products, suspended The properties are not as good as mica powder.

Third, get a little and apply it to the wrist to have a pearlescent effect; mica powder, especially sericite powder, has a certain pearlescent effect and is widely used in cosmetics, coatings, plastics, rubber and other industries. If the purchased mica powder has a poor pearlescent effect or does not have any pearlescent effect, you should pay attention at this time.
