Thermal insulation

Thermal stability of the pyrogenic silica is maintained until up to the temperature of 1200° C. Due to the microscopic size of the particles and the large distance between them pyrogenic silica is an excellent thermal insulator. Pyrogenic silica is used as an exceptional thermal insulation in such heating elements, as fire insulation of pipelines and furnace lining, air turbines, thermal insulation of storage tanks for liquefied gases at low temperatures.

For the purpose of thermal insulation are used the grades FUMISIL200, FUMISIL300, and FUMISIL380 of pyrogenic silica.
