Properties: Very flexible and supple packing, good alternative to pre-formed graphite-rings. Style 2000 combines all the advantages of pure graphite rings with the flexibilty, compressibility and ease of installation of a conventional packing; very low coefficient of friction and high thermal conductivity; extended shelf life, does not harden; chemically inert (pH 0-14) except with highly oxidizing agents. BAM approved for oxygen applications.
