pvdf filament

Hello can anyone help me I have a few questions about pvdf filament. First what kind of extruder tool head/hotend is required for successful prints? Also what printer settings should be used? And one more thing should the printer be enclosed? I am trying to print pvdf on a lulzbot taz 5 stock printer using abs printer profile settings. I am having problems getting the filament to continuously extrude, and the filament gets jamed just before the nozzle. I can unclog it but it jams back up after the toolhead has to pull the filament with any resistance.
Please someone help thanks.
