Tests of fluoropolymer coupons that have been suspended in process streams also provide useful information about the chemical compatibility of the lining. Field

Teflon®* PTFE Chemical Compatibility Chart: Check the chemical compatibility of Teflon® and PTFE with various chemicals, solvents, alcohols and other products. Polytetrafluoroethylene (PTFE) is very non-reactive and is often used in containers holding reactive and corrosive chemicals. According to DuPont, its melting point is 600 K (327 °C; 620 °F).

FFKM (Perfluoro Rubber). Perfluoroelastomers show broad chemical resistance similar to PTFE as well as good heat resistance. 2 Jul 2013 If you are unsure of the compatibility of your chemical, we recommend testing a sample of the material in question with the chemical. Updated Cast Bronze.

Or second, you can select a specific chemical to view all its compatible O-ring materials. Non-production materials such as Teflon, Airweave Breather and the bag itself would be considered F.O.D. (foreign object debris/damage) if left in layup. Because of its extreme non-reactivity and high temperature rating, PTFE is often used as the liner in hose assemblies, expansion joints , and in industrial pipe lines, particularly in applications using acids, alkalis, or other chemicals. Teflon can be machined to close tolerances, letting Vanderveer Industrial Plastics deliver the exact PTFE / FEP machined parts you need. Vanderveer Plastics' PTFE machined parts meet several ASTM requirements, including ASTM D 1710 or ASTM D 4894, for military and commercial specifications.

materials tended to leak so cork gaskets become popular and then co rkprene, followed by neoprene, nitrile rubbers (Buna - N), fluorocarbons such as Viton ®, f luoro silicones and PTFEs (Teflon

Teflon™ was discovered in 1938, developed by DuPont Co, and administered by a Chemours. In 1045 Chemours trademarked the name Teflon™, and in 1946 they started selling products coated in this heatproof and non-stick material. Teflon™ was discovered by scientist Dr. Roy Plunkett as he worked on developing a new refrigerant.

While the Teflon trademark is licensed for use in connection with certain Nalgene labware products containing authentic Teflon brand FEP and PFA polymers, we generally refer to these fluoropolymer materials by their genetic material terms on the thermofisher.com website and in most literature to ensure trademark compliance.

Black Reinforced TFE This is produced by adding 15% fibrous glass to Virgin Teflon and has a greater pressure temperature rating than Teflon. They also have a better cycle life than Teflon.
