DURLON®
9400
Carbon Filler with Pure PTFE Resins
FILLED PTFE GASKET MATERIAL
ASTM F104: F452111-A9B5E11M6 |
|
 |
APPLICATION:

DURLON® 9400 gasket material is a high performance filled PTFE designed
for use in piping and equipment in chemical, pharmaceutical, food and other general
industrial applications where resistance to highly aggressive chemicals (including
hydrofluoric acid) is required. Style 9400 conforms to FDA requirements.It can also be used as gasketing for anhydrous
hydrogen fluoride (AHF) in railroad tankcars and in plants as a material of construction
where barium sulfate filled PTFE may not prove suitable.
COMPOSITION:

DURLON® 9400 is made of pure PTFE
resins combined with carbon fillers homogeneously dispersed throughout
the compound. DURLON® 9400 does not exhibit
the cold flow problems associated with virgin PTFE yet has excellent sealability,
flexibility, non-sticking and cutting characteristics.
DURLON® 9400
also
demonstrates good electrical conducting properties.

Note: ASTM properties based on 1/16" sheet thickness except ASTM F38, which
is based on 1/32" sheet thickness. This is a general guide only and should not be the
sole means of accepting or rejecting this material. The data listed here falls within the
normal range of product properties but should not be used to establish specification
limits nor used alone as the basis of design.

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 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 personal injury. The 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. The information and
specifications contained in this website are subject to change without
notice. This revision cancels and obsoletes all previous editions. |
