General Characteristics of Dry Ground Mica power
It is highly responsive to the action of light, heat, electricity, water and other chemicals.
It transmits and reflects light to produce decorative effects and also prevents penetration of "SUN" Rays, Moisture, Heat, Gases etc. on the surface on which it is coated.
It produces stiffening effect of calendared sheets.
It has very high lubrication value and can be used as:
- High Temperature Grease, Mould Release etc. in rubber & plastics.
- Dusting Surface
- Anti friction powder of compounds.
- It produces leafing effects in liquid products due to low specific gravity and as such, remain uniformly dispersed over the surface of liquid vehicles.
- It has excellent di-electric & thermal insulation properties.
- It has very little abrasive effect and can easily get wetted by resin and dyes.
- It has an excellent anti-sticking property and as such, during vulcanization, it prevents sticking and movement of sulphur, at the same time, it permits the air bubbles to escape.
- It has re-enforcing and strengthening effect in the product with which it is mixed, and as such, it prevents rupturing and improves adherence.

Uses |
Purpose |
6 Mesh |
Oil well drilling mud |
In oil drilling operations, Mica Mud act as sealing agent and bridges the openings, this prevents loss of circulations. |
10 Mesh |
Christmas ornaments, Display materials, Artificial snow. |
Acts as flocking materials and provide glimmering effects. |

Concrete, Stone brick Asphelt Roofing felt.
Explosive & disintant absorbent automotive components break shoes. |
Proved thermal insulation and decorative finish. Prevents sticking & improves weather proofing & as Substitutes to Asbestos. |
50 Mesh |
Welding electrodes |
Results in formation of fuse able slag & provides an impermeable skin that resists the action of atmosphere condition & provides a good seal at fusion zones. |
60 Mesh |
Wire & Cables. |
In wire & cables, it provides protective coatings & line, adhesives, Lubri-Improves Dielectric properties & electrical and mechanical Ants, Plastics, Cements, Strength. |
80 Mesh |
Pipe & Enamel foundry work. |
In pipe line, Adhesive, Plastics Cement enamel etc., it increases heat & chemical resistance, co-efficient of expansion, lower growth due to water absorption provides antisag & reduces the cracking, in foundry works it act as a filter to improve the physical properties. |
100 Mesh |
Texture paints |
Attractive decorative & architectural durability, adhesion acoustical plaster water coatings. |
200 Mesh |
Tyre industry |
Inner coating of tyres. |
300 Mesh |
Paints industry |
In paint industry for glossing & heat resistant. |
