Durlon® 9000N

Durlon® 9000N is for use in process piping and equipment in chemical, pulp & paper, food & beverage and other general industrial applications where resistance to highly aggressive chemicals is required. In addition, the shape of the fillers do not allow wicking which can cause corrosion on flange surfaces and conforms to FDA requirements.

Durlon® 9000N is used extensively in chemical, pulp and paper, food and beverage and the railroad tank car industries. It has been tested and approved for liquid chlorine, caustics, liquid oxygen, and high purity applications in the pharmaceutical industry. Durlon® 9000N is designed for applications where resistance to highly aggressive chemicals is required.
Various shapes of inorganic fillers have been homogeneously blended with pure PTFE resins to give Durlon® 9000N its physical and mechanical properties. It is suitable for use in steel flanges and will not exhibit the cold flow problems associated with virgin PTFE or the hardness problems of some other filled PTFE products. It cuts easily and separates cleanly from flanges after use.

Durlon® 9000 is made with Teflon™ fluoroplastic. Teflon™ is a trademark of The Chemours Company FC, LLC used under license by Triangle Fluid Controls Ltd.
