EXPANDED PTFE GASKET MATERIAL 100% Pure PTFE Resins

ASTM F104: F428111-A9B5

Equivalent to NES 5420 / Teadit ###

 
Application
DURLON® 9600 is an EXPANDED PTFE gasket material designed for use in process piping and equipment in chemical, pulp and paper, food and beverage and other general industrial applications where resistance to highly aggressive chemicals is required.

DURLON® 9600 is suitable for use in steel flanges and flanges with irregular surfaces. Style 9600 conforms to FDA requirements.

Composition
DURLON® 9600 is made with only pure PTFE resins. It is suitable for use in steel flanges and as well as flanges where a highly compressible gasket is required. DURLON® 9600 is also suitable for sealing flanges with irregular surfaces. It will not exhibit the cold flow problems associated with virgin 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 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.
