Summary:FIELD: hermetics. SUBSTANCE: invention relates to sealing sacks when performing autoclaved molding of polymer composites at temperatures up to 450 C, for example in aircraft construction, rubber industry, and other areas. Composition contains, wt parts: methyl phenyl vinyl siloxane rubber 100, silica powder 10-30, dicumyl peroxide 5-15, and oligotrimethyl siloxysiloxane 5-15. Components are mixed on rollers and resulting mixture is pressed on metal support at pressure 3-5 kgf/cm2. Further, polyimide film in the form of bundle is rolled up to upper surface of composition material. Removal of bundle from metal support increased adhesive strength of film-metal joint. EFFECT: ensured tightness of sealed construction up to 450 C. 1 tbl, 3 ex
