Purpose and area of application Thermal insulators are intended for the use for the installations with cycle temperature changes in machine building, chemical, radio engineering industry, as well as at manufacture of building materials.

Advantages

• for the manufacture of insulators inexpensive raw material are used;
• high thermal stability;
• prolonged service life in conditions of wide fluctuations of temperatures;
• possibility of insulators manufacture with various size and complexity;
• possibility of operation the properties of alteration the composition and technological parameters of insulators material extraction.
