ABSTRACT:
A composite gasket material includes a fiber component (3-15% by wt.), an elastomeric binder component (3-15% by wt.), and a solid filer component (60-90% by wt.). The material may additionally include a phenolic or epoxy resin (up to 5 wt. %) and a silicone resin (up to 5 wt. %). The filler includes as a component a salt formed from a multivalent metal cation and a sterically hindered dicarboxylic acid. The salt ingredient typically comprises from about 20 to 80 wt. % of the filler. Gaskets made from this composite material exhibit improved sealability and thermal stability while retaining other desirable mechanical properties. These materials are able to withstand operating temperatures up to about 450.degree. C.
