Washers have a round hole and are also called washers, for example. These washers are preferably used together with hexagon head screws, machine screws, nuts, threaded rods, self-locking nuts, spring washers and body washers for Allen applications in steel and wood construction, as well as protective elements for surfaces. The cork granulate rubber mixture is characterized by good acid and weather resistance as well as limited resistance to ozone and alkalis. Compared to other sealing sheets, rubber cork is abrasion-resistant due to its composition. The material also has a high density and mechanical strength, which makes it possible to isolate airborne and acoustic noise. For this reason, the material is used as a vibration-isolating sealing material, among other things for impact soun.
