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.
