DURLON® 8300
Carbon Fiber with NBR Rubber Binder
COMPRESSED SHEET GASKET MATERIAL
ASTM F104: F712120-A9B3E22K5L311M5


APPLICATION:

DURLON® 8300 is premium grade compressed sheet gasket material that is excellent in steam and hydrocarbon services in the refining, petrochemical and power generation industries.  Other applications include oil, water, mild alkalis, mild acids, and solvents.

COMPOSITION:

DURLON® 8300 contains high-strength carbon fibers bonded with nitrile (NBR) synthetic rubber.  A release agent on both sides provides good anti-stick properties.

ANTI-STICK PROPERTIES:
Much effort has gone into improving the anti-stick release agents of all compressed DURLON® products.  All DURLON® compressed gasket materials have passed the MIL-G-24696B Navy Adhesion Test (366°F/48 hrs).

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.
 *For applications above Class 300, consult your representative.

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.
