HERMETIC ELASTIC MATERIAL Russian patent published in 2012 - IPC D06N3/14 B64D25/08 D03D1/02 

FIELD: textiles, paper.

SUBSTANCE: hermetic elastic material includes a textile basis of synthetic fibers and a polyurethane coating applied on it from the front and back side, made of a solution of polyurethane polymer and a polyisocyanate in an organic solvent, and as a textile basis it contains fabric with a fabric weight of 70-80 g/m² made of synthetic high-modulus fibers of linear density of 14.3 or 29.3 tex with a twist of 100 ± 10 tw/m, having a tensile load of not less than 1200 N and elongation at break of not more than 8%; additionally the coating comprises a filler and antipyrene, and the weight ratio of the weight gain of the polymer coating on the front and back sides are respectively 1:(2-3).

EFFECT: creation of hermetic elastic material having a high tensile load, reduced flammability, reduced hydrogen permeability while maintaining elasticity on the prototype level.
