Mica is a group of naturally occurring minerals known for their ability to split into thin, flexible layers. It is commonly used in various industries due to its insulating properties, heat resistance, and electrical conductivity. Mica is often found in shades of silver, gold, and brown and is used in products like cosmetics, paints, electronics, and construction materials. It also serves as a dielectric material in electrical applications and as a filler in plastic and rubber manufacturing.

Mica Powder in various forms is obtained by grinding/breaking mica scrap, which is a slow, costly and extremely complicated process, because of the scrap being tough and having a plate like structure. Meticulous care and precaution has to be taken so that there is no deterioration of its natural brilliance, colour and properties. Sun Minerals offer a suitable range of pure and stable mica powder that is a typical lamellar particle structure. This structure proves to be beneficial wherever a high rate of resistance against chemicals, heat and ultra violet light is required. Mica powder therefore is widely used in paint industry. Our factories are fully equipped with latest different pulverisers for processing varieties of mica powder.

1. Mica is a naturally occurring mineral known for its excellent electrical insulation properties.
2. Mica is transparent and heat-resistant, making it an ideal material for windows in high-temperature environments.
3. This mineral is often used in cosmetics for its shimmering and light-reflecting qualities.
4. Mica\'s flexibility and resistance to chemicals and moisture make it a valuable material in various industrial applications.
5. Mica is available in sheet and flake forms, with various grades and thicknesses suitable for different uses.
Mica in its processed form is one of the most versatile used materials. For over seven decades we have been processing the natural raw mica rocks to the widely used mica sheets for applications ranging from power electronics to consumer electronics.
They are made with cut condensor films that are thoroughly cleaned with the help of dc-greasing agents and are then silvered on both sides by screen printing process. There is perfect adhesion between mica and silver which results in optimum performance of the plates.
Mica flakes is mica scrap grinded into sizes ranging from 2 mesh to 30 mesh. Natural mica flakes is prepared by rotary hammer crushing machine. Mica flakes are primarily used in industries involved in the manufacturing of pearlescent pigment, concrete block fillers, refractory bricks, asphalt roofing felts, etc.
Mica flakes also vary in quality based on the quality of the mica scrap used for production. We manufacture flakes of three different qualities:
High quality made from mica scrap tested to withstand temperatures above 900 degrees C & completely white in color.
Medium quality of tested mica scrap that has a less stringent requirement of color.
Untested mica flakes without any testing temperature requirement.
Block Mica is knife-dressed mica with a minimum thickness of 7 mils (0. 18 mm). Block Mica is available in sizes up to 12 to 14 (30 to 35 cm) square. Block Mica larger than this is rare and even it was available it would be far too costly for most applications. Block Mica is available in sheets with an average thickness between 7 mils & 30 mils (0. 1 8 mm & 075 mm) Block Mica is supplied in both natural (random) and calibrated thickness as required by the customer. After splitting into a specified thickness the mica is then cut and punched to the required size and shape to meet the requirements, typically, of an electrical application.
