VM 17 Granulate

The light beige VM 17 granulate consits of pellets containing a large number of microscopic air chambers. This results in excellent insulation parameters and low density.

Belongs to the group of mica-minerals and is a natural rock. This mica-mineral contains crystal water between the single layers. The granulate results through exfoliation (expansion) of very high temperature (app. 800 - 1000 °C). Trough this process the crystal water evaporates thus separating the single layers. The volume of the granulate increases by 20-fold of the original size.

By the exfoliation process the granulate produced becomes aseptic, bacteria and germ free.

ph-Value ca. 7,5
Sintering Temperature ca. 1.260 °C
Melting Point ca. 1.315 °C
Humidity 1 - 1,5 %
Hygienic Characteristc no silicosis danger
Combustibility non-combustible class A1 conform to DIN 4102

The following table shows the thermal conductivity of VM 17 granulate in coarse grain. At higher temperatures, a finer grain is recommended due to higher heat resistance. This effect can also be achieved by thoroughly pressurizing the coarse grain to 90 % volume.
