Hi,
I'm currently working at a sheet extrusion plant, we make PS, PP and PE sheets with our sheet extruders. Now we are looking to produce PVC sheets, which are intended for thermoforming.

I am aware that I will need a different screw for processing PVC since the one I currently have is only for PS, PP or PE, and maybe the barrel will have to upgraded to withstand the level of corrosion of the PVC. I'm looking for someone that could confirm this preliminary changes that we have thought about. I thanks in advance anyone that could help.
