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 1000 C (material Puresil up to 1200 C) 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 given materials are used as replacement of asbestos in different branches of industry: oil-refining, aerospace industry, in metallurgy and shipbuilding, atomic power engineering.Silica fabrics

The enterprise manufactures a wide range of silica fabrics with the weight from 120 to 1400 g/sq.m. with the width up to 2 m with different types of finish improving their properties. One of the considerable sectors of silica fabric application — production of welding blankets, fire protective blankets, screens and curtains, casing as a thermal barrier for protection of the equipment, high temperature insulation of furnaces, turbines, screens for protection from molten metal splashes, sparks, thermal insulation.
Silica meshes
They are used as an effective filtering material for cleaning of ferrous and non-ferrous metal melts while their pouring into moulds. Usage of filters from silica mesh allows to reduce moulding defects 1,5-2 times, improve metal structure, increase its physical-mechanical and technological properties.
Silica yarns
Silica yarns are a superb raw material for weaving of tapes, fabrics, making of insulation braiding, sleeves, tubings, paddings, cords.
Silica fiber
The main field of application — production of needle felt, having a wide application in car building, metallurgy, atomic and thermal power stations, insulation in electric and combustion furnaces.
Ready-made articles made of silica materials
The most widely used are fire protective blankets designated for isolation of combustion at the initial stage of fire, as well as for extinguishing of clothes of an injured person by oxygen supply shut-off. Blankets are made from silica fabrics. Also JSC “Polotsk-Steklovolokno” manufactures other articles from silica fabrics, for example, thermal insulation sleeves for insulation of mufflers and other ready-made articles at the orders of the customers.
