4.Expanded vermiculite are usually used in industrial application as following:

Insulation in Steelworks and FoundriesGood thermal insulation, low density and its natural refractory properties combine with ease of application to make vermiculite a highly suitable material for use in steelworks and foundries. It is used for hot topping molten steel to reduce heat loss from ingots and ladles and generally as a loose-fill insulator.

Fire ProtectionVermiculite is recognised as a material particularly suited for fire protection. Vermiculite-based products range from factory made boards and panels to premixed coatings suitable for application by mechanical spray or by hand plastering techniques on a range of structures. These coatings have been used in the petrochemical industry and tunnel construction

Friction LiningsVermiculite is now used extensively in the friction lining industry (e.g. brake and clutch linings) as a safe alternative to asbestos, and plays an important role in this field.

Bitumen Coated Vermiculite ScreedsVermiculite, coated with a bituminous binder, can be used as a dry, lightweight roof screed. This type of screed has the advantages of low thermal conductivity, low moisture content and ease of placement.

Refractory ProductsVermiculite 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 1100ºC.The type of refractory products made using vermiculite are:-

pre-fired clay bonded insulation firebricks;

castable high alumina concretes for back up insulation;

high alumina bonded bricks, slabs and special shapes;

silicate bonded insulating shapes and moulded products
