Vermiculite is a hydrous phyllosilicate mineral that expands when heated. When exfoliated, vermiculite is used as a lightweight aggregate in construction materials, insulation, and horticultural applications. It is also used as a soil conditioner in agriculture and as a carrier for chemicals in industry.
In construction materials, exfoliated vermiculite is used as a lightweight aggregate in lightweight concrete, plaster, and mortar. It is also used as an insulating material in fireproofing and as a soundproofing material.
In horticulture, exfoliated vermiculite is used as a soil amendment to improve soil structure, water retention, and drainage. It is also used as a rooting medium for cuttings and as a seed starter.
In industry, vermiculite is used as a carrier for chemicals in fire retardants, brake linings, and paints. It is also used in the production of animal feed and as a filter medium in the oil and gas industry.
Exfoliated vermiculite is non-toxic and non-flammable, making it safe to use in a variety of applications. It is also resistant to temperature changes, making it suitable for use in high-temperature environments.
