SF-221 FEP dispersion is a copolymer of tetrafluoroethylene (TFE) and hexafluoropropylene (HFP). This FEP dispersion is a non-ionic surfactant stabilized aqueous dispersion. SF-221 FEP dispersion has excellent temperature resistance, corrosion resistance, outstanding chemical inertia, excellent electrical insulation and low friction coefficient and can be used for a long time at 200℃. The FEP dispersion can be applied to impregnation and spray processing.
