Neoprene Gasket Material

Content levels of neoprene can vary widely.  Application problems may occur when using blended or commercial grades of neoprene sheet of unknown quality levels in contact with oil, solvents and fuels.  In general, neoprene material resists ozone, sunlight, oxidation and many petroleum derivatives.  It provides a good resistance to weather, combustion, water and many chemicals.
