silica fiber and fabric

Silica materials are a superb high temperature insulation and can be used for a long time without changing of properties at the temperature higher than 10000С (material Puresil up to 12000С) and for a short period of time at higher temperatures.


Articles made of silica glass are extremely inert to the majority of chemical reagents, resistant to organic and mineral acids of any concentration even at high temperatures (except of hydrofluoric, phosphoric and hydrochloric acid) and weak alkalis, molten metals (except of Mg, Na, Si) and alloys. They have high chemical resistance to water and high pressure steam, are capable to absorb moisture, but are not split in the presence of water, are stable in vacuum.



The materials are used as replacement of asbestos in different branches of industry: oil-refining, aerospace industry, in metallurgy and shipbuilding, atomic power engineering.
