WebFourier transform infrared (FTIR) spectroscopy is a well-established and powerful analytical technique that allows powerful insights into a wide variety of samples. Even though FTIR … WebIf one of the fluorine atoms on TFE is replaced with a trifluoromethyl group (–CF3) then the new monomer is called hexafluoropropylene (HFP). Polymerization of monomers HFP and TFE yield a fluoropolymer, fluorinated ethylene propylene, called FEP. The effect of using HFP is to put a “bump” along the polymer chain. si wafer notch
