Uses

• Construction Sector : Mica scrap/ground mica is used in jointing cement for gypsum boards, asphaltic roofings and damp-proof seal, reinforcing filler in plaster and insulation boards, bricks, slabs and tiles.


• Welding Electrode : Our Dry-ground mica powder is highly popular in the flux coating with arc welding electrode manufacturers


• Paints : Mica is supplied in the form of powder used as filler and as an extender


• Drilling : Mica is added to drilling fluids to get off the lost circulation zones. The platy structure of mica facilitates the overlapping of particles to form a tight layer or wall, thereby preventing further fluid loss.


• Rubber Industry : Ground mica is used in the rubber industry as a dusting agent and as inert filler in the production of rubber.


• Plastic Industry : Mica is used as a filler and reinforcer in thermoplastics to improve the electrical properties, flexural strength & modulus, stiffness, heat deflection temperatures and resistance.


• Cosmetic Applications : Dry-ground mica powder is used in small quantities in cosmetic applications due to its high resistance to the effect of the sun rays, moisture, gases, water and other chemicals,


• Decorative Coating : Dry-ground mica powder in small quantity is also used to improve the decorative coating and luster of wallpaper, printing and ceiling papers, etc.


• Foundries : Small quantities of scrap mica/ground mica are also used in industries like foundries as coating to foundry cores and moulds, as a dry lubricant to prevent hot bearings from seizing up.
