Micashield is an aqueous dispersion of exfoliated Vermiculite.
Vermiculite is the name given to a group of hydrated laminar aluminium-iron-magnesium silicates. Raw vermiculite consists of thin, flat flakes containing microscopic layers of water.
When vermiculite is exfoliated thermally, the microscopic layers of water are explosively removed and the flakes expand to worm-like, light weight particles. Chemical exfoliation also leads to expansion but the result is individual platelets with a high aspect ratio that are freely suspended in water.
In dried, powder form, the high aspect ratio of Micashield provides a material additive which can offer can offer significant improvements to the fire-resistance of a variety of materials. Micashield is a non-toxic and easy to use product that is environmentally friendly.
Micashield is available in numerous formats, each suitable for the specific application type. Carefully controlled processing techniques ensure that all the Micashield range of products exceed the most exacting tests that each fire protection sector demands.
Micashield is available to fulfil requirements in Coatings for Industrial textiles, Wet and Dry Fire Retardant additives and Passive Fire Protection situations.
