Gasket Material

Most of todays non-asbestos gasket materials contain either Kevlar, an aramid fiber, fiberglass, carbon, graphite or another mineral fiber. Regardless of the manufacturer, the basics are the filler and the elastomer used. While no two compounds (or the % of filler) are identical, the basic Elastomers are: NBR (Buna-N), SBR, EPDM or Neoprene. If you examine which material you need (as defined by the application) and select the non-asbestos gasket material with that elastomer you will usually do well. This method will also allow you to select a competitive brand that will serve your application. No two materials are identical so caution must always be exercised.
