Durlon 9200
Durlon 9200 is a filled PTFE gasket material designed for use i n process piping and equipment in chemical, pulp and paper, food and beverage and other general industrial applications. It can be used where resistance to highly aggressive chemicals is required.
Durlon 9200 is suitable for hydrofluoric acid service at moderate concentrations and temperatures or where a barium sulfate filled PTFE gasket material is specified. This product conforms to FDA requirements as well as receiving BAM oxygen service & TA-luft (VDI Guideline 2440) certifications.
Barium sulfate fillers are homogeneously blended with pure PTFE resins to give Durlon 9200 its physical and mechanical properties. Testing shows the fillers to be more evenly dispersed than filled PTFE with layered construction. The result is more consistent physical and mechanical properties without the voids, separation and chemical compatibility problems found in layered filled PTFE. It is suitable for use in steel flanges and will not exhibit the co ld flow problems associated with virgin or generic skived PTFE, or the hardness problems of some other filled PTFE products.

Warning: Durlon® gasket materials should never be recommended when both temperature and
pressure are at the maximum listed. Properties and applications stated are typical. No applications
should be undertaken by anyone without independent study and evaluation for suitability. Never use
more than one gasket in one flange joint and never reuse a gasket. Improper use or gasket selection
could cause property damage and/or serious injury. Data reported is a compilation of field testing,
field service reports and/or in-house testing. While the utmost care has gone into publishing the
information contained herein, we assume no responsibility for errors. Specifications and information
contained in this flyer are subject to change without notice. This edition cancels and obsoletes all
previous editions.
