Useful but varying mechanical properties are maintained from -400 to +500 deg F. As with most man-made materials extreme cold renders the finished product stiff and ridged, while extreme heat renders the finished product soft and pliable. This is normally only a concern during initial assembly. Applications above 500 deg F should be avoided: Harmful, …
Unfilled, virgin resins are considered FDA compliant, for use in food-processing equipment such as sanitary or flange gaskets.
PTFE resins are essentially chemically inert. Within the recommended operating temperature range the only chemicals known to react with these resins are molten alkali metals, fluorine in any form, chlorine tri-fluoride, and oxygen di-fluoride.
Parts molded of PTFE are utilized in hydraulic and pneumatic cylinders, motors, pumps and valves. They reduce equipment wear, fluid loss, and frequency of packing changes. Suitable for static or dynamic (linear or rotary) applications. A complete V-ring seal requires at least one V-ring, one male adapter, and one female adapter. The female adapter provides …
