THE LAMINAR SEALING MATERIAL FOR A GASKET Russian patent published in 2004 - IPC

FIELD: production of the laminar sealing materials for gaskets. SUBSTANCE: the invention is dealt with production of the laminar sealing materials (paronites) and different gaskets made out of them, intended for operation in the sealing joints with the flat sealing surfaces, in process of operation of which the laminar sealing material is exposed to variable thermal and mechanical actions such as the periodical compressions, heatings, etc. The laminar sealing material is composed of several flat composite layers with a die made out of a rubber vulcanizate. At that the surface layer of the material has an improved recoverability. EFFECT: The laminar material has an improved sealing ability. 2 ex
