EXPANDED PTFE GASKET MATERIAL

9600 Expanded PTFE Gaskets

100% Pure PTFE Resins

ASTM F104: F428111-A9B5
9200w-097452-edited.png

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. Durlon® 9600 (including branding) conforms to FDA requirements.

COMPOSITION:

Durlon® 9600 is made with only pure PTFE resins. It is suitable for use in steel flanges 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.

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.
