Materials used in the pump and pumping systems must be chemically compatible. The data provided for the chemicals is at 70ºF (21ºC), unless otherwise noted. If your temperature differs from this, it may affect the compatibility of the fluid with the given pump materials by accelerating the reaction. Versatile Options for Diverse Applications.

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 generic material terms on the thermofisher.com website and in literature to ensure trademark compliance.

4 Thus, oxidation effects on materials may be similar for both low-temperature hydrogen peroxide gas plasma Ten polymeric materials including EPDM, Nylon 6,6, Buna-N and other materials marketed* as TFE-Teflon® (PTFE), Kel-F® 81 (PCTFE), Vespel® SP-21, Viton® A, Viton® A-500, Fluorel®, and Neoprene® were systematically evaluated for their oxygen compatibility property. 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. Carbon Filled PTFE was developed to provide a PTFE based material with improved mechanical strength.. PTFE on its own has excellent frictional properties, elasticity and wear resistance but relatively poor mechanical strength and tends to fail in high PV applications.
