Vermiculite is a natural mineral known for its exceptional heat and fire resistance. Raw vermiculite is a lightweight, absorbent material that expands when heated. Vermiculite possesses excellent insulation properties, making it ideal for construction and horticulture. Raw vermiculite is often used as a soil conditioner, enhancing water retention and aeration. Vermiculite's unique exfoliation property allows it to be used in various industries, including agriculture, construction, and insulation.

Global Minechem Corporation provides Vermiculite in India. Vermiculite is a term functional commercially to micaceous minerals which are alteration products of biotite or phlogopite micas, produced by the removal of alkalies and addition of water. Vermiculite differs from mica in its attribute property. The crude vermiculite is predominantly exfoliated before utilization. For converting raw vermiculite into a product fitting for industrial use, it must be exfoliated or lengthened by heating, a procedure also called as ‘exfoliation’.

Raw vermiculite: An inorganic, naturally occurring mineral with remarkable heat resistance and insulation properties. Lightweight and expandable: When heated, raw vermiculite expands, making it an ideal additive for construction materials. Fire-resistant: With a high melting point, it\'s an effective fireproofing material. Excellent moisture retention: Raw vermiculite\'s moisture-absorbing qualities make it valuable in horticulture and gardening. Natural insulation: Used for its insulating properties in the construction industry, it helps conserve energy and improve thermal performance.
Mica are sheet silicates historically significant for their ability to be split into large, thin sheets that are uniquely useful for their electrical, thermal, and mechanical properties. They have high electrical and thermal insulating properties; they are resistant to chemical attack; they can be split into transparent or optically flat films; and they can be cut or stamped to shape. Uses of mica: 1- Joint cements: muscovite is used in drywall joint compounds, where it contributes to consistency and workability, smooth surface finish, and resistance to shrinkage and cracking. 2- Coatings Fine-ground, -325 mesh and micronized mica grades are used in paint as a pigment extender and for dry film reinforcement. The inert, platy mica improves suspensi on stability, controls film checking, chalking, shrinkage, and blistering, improves resistance to weathering, chemicals, and water penetration, and improves adhesion to most surfaces. Coarser grinds are used in textured paints, and wet-ground mica is used in high quality exterior house paints. High aspect ratio grades are preferred for porous surface sealers to seal pores, control penetration, and reduce sagging and film cracking. 3- Plastics Finely ground, -325 mesh and micronized micas are used in plastics to improve electrical, thermal, and insulating properties. Mica is considered the most effective mineral for reducing warpage and increasing stiffness and heat deflection temperature in plastics. In general, mica reinforces crystalline better than amorphous polymers. Best results are obtained with nonpolar polymers when mica is pretreated with a coupling agent to improve wetting. Mica is used in both thermoplastics and thermosets. Its largest single use is in polyolefins, even though it requires stabilizers to prevent degradation of polypropylene. 4- Drilling fluids Coarse, hammermilled (+10 mesh) mica is used in waterbased oilwell drilling fluids to prevent fluid loss into porous rock formations.
