Polyshell-03: Graphite filled PTFE has superior wear and heat resistance. It is non abrasive and has a low coefficient of friction and can be used in dry environments.

PolyShell-05: Carbon-graphite filled PTFE has a higher extrusion resistance than PolyShell-03 with good wear and seal life.

PolyShell-07: Glass-Moly filled PTFE is very tough and long wearing. Is abrasive but can be used in high pressure applications.

PolyShell-08: UHMW Blend is an excellent cryogenic seal material. It is tough and durable but with limited heat and chemical resistance.

PolyShell-09: Polymer filled PTFE has excellent wear characteristics. It is non-abrasive and recommended for moderate to high speed applications.

PolyShell-10: Polymer filled PTFE has excellent heat and wear characteristics for high speed applications.
