Vermiculite is a natural mineral that has several applications in construction, horticulture and industry. The mineral belongs to the group of phylosilicates and has the property of greatly expanding when heated. This process is known as exfoliation, a procedure that results in an expanded, light material. The colour of vermiculite depends on the origin of the mineral and varies between brown and beige.
Applications
Because of its versatile qualities, vermiculite has various applications as an ecological material in various fields:
Fire protection applications
Due to its refractory properties, vermiculite is often used in fire-resistant materials.
Horticulture
Vermiculite is used in horticulture as a soil conditioner. It optimises soil aeration and has good water retention, which is beneficial for plant and crop growth.
Packaging
Vermiculite is also used as a packaging material, especially when packing fragile and dangerous goods.
Industry and construction
Due to its light weight and insulating properties, vermiculite is often added to building materials and is frequently used as insulation material. VermiPrime is supplied as a semi-finished product in bulk for use in own products
