DURLON 9200

Barium Sulfate Filler with Pure PTFE Resins

FILLED PTFE GASKET MATERIAL

ASTM F104: F452111-A9B5E11K6M6

APPLICATION:

DURLON

9200 is a filled PTFE gasket material designed for use in aggressive chemicals.

Including caustics, hydrogen peroxide, sodium hypochlorite, nitric acid, liquors and digester in

pulp and paper service. Applications In the chemical, pharmaceutical and plastics industries

include butadiene, hydrofluoric acid, vinyl chloride, methyl methacrylates, and styrene. It is

also used extensively in

railroad tankcar applications and can be used where resistance to

highly aggressive chemicals is required.

DURLON

9200 is also used for hydrofluoric acid service at moderate concentrations and

temperatures or where a barium sulfate filled PTFE gasket material is specified within a

temperature range of –350°F to 520°F (-212°C to 271°C), or with pressure up to 1500 psi (10.3

MPa). Style 9200 (granite white, branded) conforms to FDA requirements.

COMPOSITION:

Barium sulfate fillers are homogeneously blended with pure PTFE resins to give DURLON

9200 its physical and mechanical properties. Independent testing has shown the fillers in

DURLON

9200 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, will not exhibit the cold flow problems associated with virgin or generic skived PTFE or

the hardness problems of some other filled PTFE products. It has excellent sealability, cuts

easily and separates cleanly from flanges after use.

Warning: Durlon gasket materials should never be recommended when both the temperature and the pressure are at the

maximums listed. Properties and applications shown are typical. No application should be undertaken by anyone without

independent 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 personal injury. The data reported is

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. The information and specifications contained in this

website are subject to change without notice. This revision cancels and obsoletes all previous editions.
