Silica fabrics
Application: silica materials possess excellent high-temperature heat-insulation properties and keep heat. They are used in many industries. These materials are good thermal barrier and the best means of protection from fire and heat power's influence during processes, connected with high temperatures.
Peculiarities of materials: silica materials have low thermal conductivity, are good electro-insulation materials at high temperature and enlarged moisture, can be used for a long period of time at 1000 °C and at more high temperatures for a short period.

Cord of silica thread (ShTK)
Application:
Gasket cords from silica thread (ShTK) as thermal barrier in different processes, run at high temperatures (up to 1150 °C). Specifically, when gasketing doors of thermal cells, moving elements of furnaces, compensation joints of lining of these furnaces etc.
Special features of materials from silica thread.
materials are resistant to heat stroke and high radiation , at high temperatures and heightened humid they are perfect electric-insulation materials, can be used for a long period of time at 1150 °C and at more high temperatures for a short period. Articles from silica thread are resistant to organic and inorganic acids even at heightened temperature (except hydrofluoric, phosphorus, hydrochloric acids) and weak alkalis. Materials from silica thread are splendid substitutes for asbestos, are not harmful for health of those, who utilize them.
Gasket cords are elastic, supple, humid-, vibration-resistant, resist attack by solar radiation, very adhesive to high-temperature glues.
