Abstract: Method for obtaining the foamed organosilicon compositions, involving mixing of organosiloxane rubber (OR), organosilicon joining agent (JA) and modifier (M). Agents acting like (OR) are represented by polyorganosiloxane block-copolymers having formula as follows: {[R1SiO1.5]a[R2(OH)SiO]b, [R3R4SiO]c}n, where: R1R2R3R4 are aliphatic, aromatic radicals having from 1 to 6 atoms carbon; n is an integer from 30 to 360; c=1; a is selected from the 0.019-3.760 interval; b is selected from the 0.008-0.240 interval; or the mixture of the above block-copolymer with the “&agr;”, “&ohgr;”-dihydroxypolydiorganosiloxane in the ratio of (0.05-0.
