Modified PTFE (TFM)

mPTFE (modified PTFE) is a chemically modified version of PTFE. The modifications occur in the molecule itself and offer enhanced features that play a role in special applications, especially in the area of safety and reliability.

The best-known brand name in the past was TFM® of Dyneon/3M. As they stopped this activity entirely, Vanéflon is able to offer you a valuable alternative.

One factor that makes mPTFE special is the density of the molecular structure.  This results in a significantly lower rate of gas permeation for the same thickness of material when compared with PTFE.  This characteristic is extremely important when used in a highly corrosive environment.  With its dense molecular structure, mPTFE also offers a smoother surface finish than PTFE.

Furthermore, mPTFE has a slightly higher spring rate, but noticeably better fatigue properties and better stress recovery. In addition, it is even weldable.

 

Vanéflon is your partner for rods, tubes, sheets and machined parts.
