Mica Powder Improve The Air Tightness and Insulation Property of Plastics

The Wet Ground Mica Powder has excellent thin slice shape, the thickness of microcrystal is nano meter, the effective barrier area is great. After adding wet high purity mica powder into the plastic, the air tightness will be greatly improved. This can be used to make coke bottles, beer bottles, medicine packaging bottles, moisture-proof packaging materials and many similar special plastic packaging materials. 

In order to make full use of unique properties of wet mica powder, many valuable new plastic products can be developed, to form many valuable application technologies. The insulating property of the mica powder with high iron content is low, so it should be avoided to use. Dry Ground Mica Powder is not washed, the iron content is high, so it is not suitable to use this kind of mica powder.
