NEOFLON PCTFE has the best performance of gas barrier properties, especially for low permeation capability to moisture and steam atmosphere compared with other plastics.
The heat resistance and chemical resistance capabilities are lesser than PFA and FEP, however, mechanical characteristics (especially hardness) are superior.
