Gasket Designs and Applications Using Flexible Graphite

High performance gasket technology has been based on elastomeric-bonded, fiber-filled- fibers historically affording the optimum price-performance benefits. Binder-free, non-asbestos, flexible graphite has temperature-pressure capabilities superior to those of asbestos-based products and can be made into a wide range of useful gaskets with simple fabrication techniques. Essential design characteristics of flexible graphite are overviewed and compared with those of elastomeric-bonded asbestos and non-asbestos materials. Several specific head gasket and exhaust sealing applications are cited.
