ABSTRACT:
This invention relates to a composition suitable for use in friction elements and comprises a frictional material and a binder, the latter being a blend of a polyvinyl alkyl ether with a phenolic resin and optionally a rubber.
Compared with conventional friction elements based on organic polymers, the elements produced using the compositions of the present invention shows increases in flexural strength of up to 50% with no loss in wear or friction performance.
