Modified PTFE offers many advantages over PTFE. Lower deformation under load, better fatigue performance, easier to weld, better transparency, higher elongation and higher dielectric strength. Modified PTFE like PTFE has excellent chemical resistance and a very low coefficient of friction.

Modified PTFE or TFM, is a high-density copolymerized material. It has low gas permeation and reduces cold flow. Often used in the medical field as an artificial blood vessel graft and in other applications where biocompatibility is required. TFM is also FDA and USP class VI suitable.

3M™ Dyneon™ TFM™ Modified PTFE Powder TFM 1700 is a non-free-flowing compression moulding powder for applications like shaped parts, cylinders or blocks, skived films of >20 µm, linings in the chemical processing industry (CPI) and seals, and is suitable as basic material for filled PTFE (compounds). Processing Recommendations

Derived from standard PTFE, modified PTFE is a copolymer of tetrafluoroethylene and a small quantity of a perfluorinated modifier (perfluoropropyl vinyl ether, PPVE). The modifier content is less than 1%. Modified PTFE can be considered a second-generation PTFE.

DyneonTM TFMTM PTFE is a chemically modified PTFE that offers enhanced properties for the electrical, mechanical, automotive, semiconductor, and chemical industries, while retaining all of the proven advantages of conventional PTFE.

TFM 1600 PTFE is the blend chosen by APV as it exhibits properties that are ideal for ball valves in a wide range of applications. In addition, TFM complies with FDA and 3A requirements.
