Applications
Raw Vermiculite
- Heat Retaining Covers, thanks to its refractory properties, good thermal insulation and low density, vermiculite is used in steelworks and foundries, for hot topping molten metal to reduce heat loss from ingots and ladles.
- Gaskets and Seals; ground or milled vermiculite may be used for the production of anti-
drumming coatings; condensation control paints; high performance gaskets and seals and for upgrading the fire resistance of organic foams and other polymer based systems.
Exfoliated as is
- Horticulture
Seed Germination use Fine Vermiculite mixed with seed composts at a rate of up to 50%. This will aid aeration, improve water-holding capacity and speed up germination times. Vermiculite can also be used on its own to cover seeds once sown.
Root Cuttings use Medium Vermiculite mixed with peat-based growing media at a rate of 10- 25% to aid aeration and improve water- holding capacity. It is particularly useful for soft- wood cuttings and leaf cuttings of many gesneriads and begonias. Hard to root shrubs, including some magnolias and rhododendrons, can be rooted in a 50/50 mixture of Vermiculite and Perlite.
Potting Compost Use Medium or Coarse Vermiculite mixed with peat-based substrates at a rate of 20- 25% to improve aeration and aid water- holding capacity. Vermiculite also helps to absorb excess nutrients and improves re- wetting. - Roof/Attic Insulation
loose fill Insulation. Loose fill vermiculite can be used between joists in lofts for house insulation. The free flowing properties of exfoliated vermiculite make installation very simple. The insulating properties of vermiculite significantly reduce the loss of heat in cold weather and keep the interior cool in hot weather. It also functions as a sound absorbent material. - Absorption Material (waste water treatment, Animal feeds, Flammable material Spill kits)
Sorbents are insoluble materials used to recover liquids through the mechanism of absorption or adsorption or both. Absorbents are materials that pick up and retain liquid causing the material to swell (50 percent or more). Absorbents are insoluble materials that are coated by liquid on its surface. To be useful in combating oil spills, sorbents need to be oil attracting.
Although they may be used as the sole clean up method in small spills, sorbents are most often used to remove final traces of oil. Vermiculite is a natural inorganic sorbent and can absorb 4-20 times their weight in oil.
Vermiculite is ideal for removal of chemical spills, absorption and removal of oil spillages from floors, treatment of nuclear waste material, transportation of hazardous chemicals, carriage of liquid fertilisers, herbicides, insecticides, and vegetative oils for animal feed stuff, absorption of molten materials and as fat absorbent for barbeque bases - Loose Fill Packaging
Exfoliated vermiculite is a useful packaging medium. Not only is it lightweight, clean and easily poured around irregular shaped objects, it also provides a good baffle against shocks caused by impact and improper handling.

Waterproofing
Vermiculite, coated with a bituminous binder,can be used as a dry,lightweight roof and floor screed.This type of screed has the advantages of low thermal conductivity, low moisture content and ease of placement.
Light weight concrete
Vermiculite concretes are lightweight, have good insulating properties and are intrinsically fire resistant. Vermiculite concretes may be used for in situ roof and floor screeds and in the fabrication of pre-cast products.
Light weight refractory monolithics
Vermiculite based mixtures concretes may be used for the fabrication of precast products, as gunning materials and as a replacement for insulating fire brick in a wide range of applications.
Fire Retardants
Vermiculite plasters or spray materials can be made with gypsum, Portland cement or various other formulations. Vermiculite also improves the spall resistance of plasters due to the ability of vermiculite particles to accommodate dimensional change. Vermiculite plasters, whether gypsum or cement based, can be applied by hand or by spraying machine. Being a non-abrasive aggregate, vermiculite is well suited to spray application and the sprayed plasters can have an attractive decorative appearance. - Processed shapes
Refractories
Vermiculite for refractory and high temperature insulation is normally bonded with alumina cements, fire clays and silicates to produce a wide range of vermiculite products which, depending on type and application can withstand hot face temperatures of up to 1,200ºC.
Building Insulation
Vermiculite based products such as factory made boards and panels are frequently used in building construction.
Brake Linings
Vermiculite is now used extensively in the friction lining industry (e.g. brake and clutch linings) as a safe alternative to asbestos.
