Water soluble heat-insulation for multiple commercial applications

A British company has created and patented an advanced heat-insulation material that can adhere to almost any surface, can be moulded around complicated shapes and can also be machined to specific user needs.
Water soluble heat-insulation for multiple commercial applications
Otherwise known as Barrikade, this insulation material is composed from vermiculite particles (inorganic aluminium iron-magnesium silicate) and a sodium silicate binder. The resultant product is a lightweight heat-insulation material that can be incorporated into fire doors, electro-mechanical insulation shielding and cavity wall insulation etc.

The manufacturing process is configured around a two-stage process. In the first stage, the vermiculite particles are mixed with a blended silicate binder and then spread out to cure in an oven at about 100 degrees Celsius. During the second stage, more binder is added to the pre-coated vermiculite and finally it is moulded to the required shape and size.

Further, and because it is a silicate-based system, meaning that it is water-soluble, the material properties of this heat-insulation product can be re-cycled. The product is immersed in water until the silicate binder dissolves and the vermiculite particles separate; the vermiculite particles can then be dried and eventually re-used.

Barrikade's fire resistance properties are further enhanced because during extreme heat exposure it does not emit any traceable toxic fumes. Thus this material is ideally suited to sandwich components for fire doors. In the UK market alone, some five hundred thousand fire doors are manufactured every year.

Another application for Barrikade is for cloaking military vehicles whereby gun barrels and missile launchers realise a reduced heat exposure, thus minimising enemy to target acquisition. The commercial application list is seemingly endless, and the latest development is sought in the automobile industry for use in catalytic converters.
