PTFE (also known as PTFE, Teflon, Teflon, F4), PTFE is a polymer polymerized from tetrafluoroethylene, is a transparent or opaque wax similar to PE, Its density is 2.2 g/cm3 and its water absorption is less than 0.01%. Its chemical structure is similar to that of PE except that all hydrogen atoms in the polyethylene are replaced by fluorine atoms. Due to its high energy and stable performance, the C-F bond has excellent chemical resistance.
