Which domains use VERMICULITE?
Passive fire protection products
GRANUTEC® vermiculite is particularly suitable for fire protection, especially in the petrochemical industry and tunnel construction. Numerous official tests have confirmed the fire resistance of products made of vermiculite, ranging from prefabricated boards and panels, to fire doors, mixed and coated plasters, which can be applied manually or by spraying.
Lightweight and insulating concrete
GRANUTEC® vermiculite mixed with Portland cement and water (or a resin if necessary) in proportions that vary according to the desired strength and insulation factors produces a concrete that is light, insulating and fire-resistant. This type of concrete is used in roof or floor coverings, as well as in the manufacture of pre-molded products. It is easy to mix and lay both manually and with mechanical equipment.
Thermal and sound insulation
GRANUTEC® Vermiculite – can be used as loose fill insulation instead of conventional insulation such as glass wool, in block walls, doors, prefabricated or existing partitions, or loose fill insulation in attics and floors. Its flow properties make it very easy to install, while its insulating properties significantly reduce heat loss in winter and keep the interior cool in warm weather. It also functions as a sound insulator and against moisture transfer.
Absorbent and Packaging
GRANUTEC® Vermiculite, a practical packaging material (light, clean, non-combustible, inorganic) that easily fills the space around irregular shapes, provides good shock absorption for fragile and/or sensitive materials that need to be protected, such as hazardous chemicals, where it is also possible to protect against accidental spills of varying sizes thanks to its high absorbency.
GRANUTEC® Vermiculite can retain up to 450% of its weight in water and is also perfectly suitable for the storage of fruits, bulbs and tubers.
GRANUTEC® Vermiculite, added to Portland cement or gypsum, produces coatings that can be applied manually or sprayed with advantages over conventional coatings:
- lighter weight
- better thermal insulation
- better adhesion compared to a wide range of substrates
- excellent fire resistance
- protection against condensation
Steelworks and Foundry
GRANUTEC® Vermiculite, thanks to its intrinsic qualities (good thermal insulation, low density, natural refractory properties), combined with the simplicity of application, is an ideal covering for molten metal, which reduces the loss of calories in the ladle, tundish or ingot mould.
Friction Lining and Refractory Products
GRANUTEC® Vermiculite, which is safe for brake and clutch linings, is widely used in combination with other minerals as a substitute for asbestos.
GRANUTEC® Vermiculite, bonded with alumina cements, refractory earths and silicates, can be used for a wide range of products with a temperature range up to 1100°C on the hot side: bricks, concrete insulation, alumina bonded bricks, special shapes and boards, silicate bonded insulation shapes, moulded products, shapes and blocks.
GRANUTEC® Vermiculite, flowable, sterile, non-irritating, non-toxic and absorbent, is the ideal carrier of a wide range of nutrients such as concentrated fat, vitamin preparation and molasses. Its high volumetric efficiency and high liquid retention combined with easy handling make it very easy to mix with other materials.
- Anti-caking and anti-caking agent.
- Support for finely ground dry materials.
- Inert carrier for medical products and nutritious liquids.
- Regulator of calorific value
GRANUTEC® Vermiculite can improve or correct soil deficiencies (e.g. lighten a clayey soil), while retaining moisture and nutrients to feed roots, shoots and seeds, ensuring rapid and maximum growth. It is a carrier and liberator of fertilizer, herbicide and pesticide.
GRANUTEC® Vermiculite has remarkable Cationic Exchange Characteristics, and can provide plants with ammonium, potassium, calcium and magnesium.
Horticulture and Hydroponics
GRANUTEC® Vermiculite is the ideal medium for stimulating root growth and young plant production, in sand, peat and infertile soil, regulating or controlling temperature and humidity changes. Commonly used in composts: helps aeration, improves the retention of nutrients, and improves the growth of plants.
GRANUTEC® Vermiculite is a classic hydroponic growing medium.
