Mica Powder 

Daruka Isolants - Manufacturer and exporter of mica powder. India is the biggest producer of muscovite sheet mica in the world. This type of mica is also called Potassium Mica and is the best variety available in the global world. It is tough, chemically inert, immune to climatic variations, non toxic, transparent and water proof. By virtue of these unique qualities, it can be reduced to very small thin particle having diameter to thickness ratio as high as 25 to 1. It can therefore, be transformed into coarse, medium & fine varieties of flakes and powder by dry process of pulverization and there by it renders itself to wide commercial application in these forms.

muscovite sheet mica, dry ground mica powder, wholesale potassium mica, wholesale mica powderMica powder in various forms is obtained by grinding/breaking mica scrap, which is a slow costly & extremely complicated process, because of the scrap being tough and having plate like structure. Meticulous care & precaution has to be taken so that is no deterioration of its natural brilliance, colour and properties. Daruka mica factories for processing different varieties of mica powder are fully equipped with latest grinding media, pulverizers and classifiers. Powder testing equipments there to control quality, mesh size etc. Daruka mica personals always supervise the production, packing, transportation of raw material to end product for the satisfaction of the customers.
