Vermiculita

 

Vermiculite Granules exfoliated at temperatures of 980C / 1040C are available in standard U.S. granule size #3.

 

With a very low conductivity and relatively high fusion point, Vermiculite Granules is a useful bulk insulation for blast furnace hot metal transfer equipment and continuous casting tundish insulation.

 

It is also used as a topping for ingot molds, as an insulating base for hot ingot transfer and even loose fill over soaking pit covers.

 

In addition, Vermiculite Granules are used in a wide variety of packing and shipping applications.
