THERMAL- PROTECTIVE MATERIALS

THERMAL PROTECTIVE MATERIALS BASED ON QUARTZ (TZMK) AND SILICA (TZM) FIBERS

The TZMK materials based on superfine and superpure quartz fibers have been developed to ensure thermal insulation of the space shuttle BURAN. The materials have successfully undergone flight test - only 10 tiles out of 36000 needed to be replaced after the BURAN landing. Nowadays the material TZM-23M based on cheaper silica fiber has been developed and is being produced. It compares well with the TZMK-10 material.

high resistance to corrosive media and heat shock
low density and thermal conductivity
high porosity
radioparency
high insulating properties

for lining high-temperature furnaces including thermoelectric and induction furnaces
as thermal-protective elements of stomatological furnaces
as insulation elements in lift tubes for gas condensate wells used in permafrost zone
for thermal insulation of chemical reactors, gas-holders, refrigerators, safes, etc.

Owing to high thermal-insulation properties of the TZMK and TZM materials, the saving of energy and the decrease of overall dimensions and weight of the heating plants are achieved.
