Graphite filling strip is supposed to used in high temperature environment,
PTFE filling strip is for acids and other corrosive mediums
Non - asbestos its use increased when the health problems with asbestos became known. Only recommend for low temperature less severe applications due to the rubber content .
Ceramic is in extremely high temperature applications.The filler is not so common as it cannot achieve the same leak tightness as graphite
