Vermiculite
Vermiculite is a natural mineral that has several applications in construction, horticulture, and industry. This mineral belongs to the group of phyllosilicates and has the property of expanding significantly when heated. This process is known as exfoliation, a procedure that allows for the production of an expanded and lightweight material. The colour of vermiculite depends on the origin of the mineral and varies between brown and beige.
Applications
Due to its versatile qualities, vermiculite has numerous applications as an eco-friendly material in various fields:
Fire protection applications
Due to its refractory properties, vermiculite is often used in fire-resistant materials.
Packaging
Vermiculite is also used as packaging material, particularly for the packaging of fragile and hazardous products.
Horticulture
Vermiculite is used in horticulture as a soil amendment. It optimises soil aeration and allows for good water retention, which is beneficial for the growth of plants and crops.
Industry and construction
Due to its lightness and insulating properties, vermiculite is often added to building materials and is frequently used as an insulation material. VermiPrime is supplied as a semi-finished bulk product for use in its own products.
