In the light of the mounting publicity given to the health hazard from fine asbestos dust in recent years, GOETZE AG has at an early date developed non-asbestos soft materials for gaskets, especially cylinder head gaskets.Two particularly important material alternatives (graphite foil and non-asbestos fiber soft materials manufactured on papermaking machines) are considered in depth.The remainder of the paper discusses in detail the functional characteristics important to cylinder head gaskets of the non-asbestos gasket materials Kostafol (graphite). ASTADUR AF and ASTADUR AF45. The functional advantages and disadvantages of these materials are outlined.
