JOINT EN DEUX MATERIAUX, SANS AMIANTE, ET PROCEDE POUR SA FABRICATION

摘要

A gasket formed from a perforated core sheet having a first facing layer formed from a material having a relatively high degree of thermal conductivity on one side thereof and a second facing layer formed from a relatively compressible, non-asbestos gasket material on an opposite side thereof. The facing layers are attached to the core by mechanical retaining means. The retaining means can be formed as a pair of opposed tangs on opposite sides of each perforation in the core or as a dome-shaped structure having an aperture formed in an end thereof.
