pressure and temperatures. It has been found out

that potassium hexatitanate and potassium octatitanate

fibers should be used together. In this way, the perfor-

mance of the mixture can be increased considerably.

13.5.2 Gaskets

Gaskets and other seals are required for use in many

applications where adjacent surfaces are to be sealed

to prevent fluid or gas leakage [81]. Composite gasket

materials made by a wet laid process are comprised of

a fiber component which is distributed within an elas-

tomeric binder matrix, together with property improv-

ing solid fillers [82].

The content of the fiber component is typically

3–15%. The elastomeric binder ...
