Modified PTFE (TFM)


Modified PTFE or TFM is chemically modified version of PTFE that has modified characteristics in addition to the characteristics property with that of virgin PTFE. Modified PTFE is modified in the molecule and offers enhanced features that play a role in special applications, especially in the area of safety and reliability. Applications can be found in the sealing technology, construction and/or semiconductor industry.
