PRODUCTION of LTD LIRSOT
Of high thermal- and fire proof polyimide fibers Arimid, Pion and Tvim

POLYIMIDE FIBERS AND TEXTILE ARTICLES MANUFACTURED ON THEIR BASE:

   Have high fireproof;

   Their fireproof degree exceeds all known organic materials;

   Long term exploitation temperature up to 350oC;

   Are resistant to the open flame and the heat stroke with temperature up to 1 000oC emitting no smoke;

    Maintain high strength and elasticity at the temperature of the liquid nitrogen;

   Have low thermal conductivity;

    Are highly resistant to the hard radiating and ionizing rays;

    Are resistant to effects of the pathogen funguses and mould.
