PTFE resin (polytetrafluoroethylene) belongs to the class of paraffinic polymers in which hydrogen is,
to a part or completely, replaced by fluorides. The original PTFE resin was invented in 1938 by DuPont
and baptized by the name Teflon. PTFE has an extraordinary resistance against chemicals and has
one of the lowest coefficients of friction of all materials known to us today.
