FIELD: chemistry.
SUBSTANCE: invention relates to porous products, containing porous fluoropolymer and coherent irregular thermoplast grid. In one example of realisation coherent irregular grid is fixed to extended fluoropolymer only in part of adjacent area. In other version of invention coherent irregular grid represents film, containing coherent irregular grid. In one example of realisation coherent irregular grid has surface roughness, determined by Sp value larger than 35 mcm.
EFFECT: invention makes it possible to obtain porous products with improved characteristics of structural integrity and air-permeability.
