FIELD: chemistry.
SUBSTANCE: invention relates to hermetising polymeric composition, which is applied in machine-building and construction. The said composition includes with definite ratio of components: forpolymer, simple oligoether, filler and wastes of elastic foampolyurethane; as forpolymer it contains forpolymer based on polyoxitetramethilenglycol and toluilendiisocyanate, as simple oligoether - simple oligoether based on glycerol, propylene oxide and ethylene oxide of molecular weight 3600, and additionally contains polyisocyanate type B, tiodiethylene glycol and tin octoate. The composition contains definite composition of components, as a result of which breaking strength of hermetics based on such composition increases 2-3 times and remanent elongation reduces 4-6 times.
EFFECT: increase of breaking strength and reduction of remanent elongation of hermetics.
