PVC Purge: GUARANTEED CARBON REMOVAL
PVC Purge shifts stubborn carbon/plate out from extrusion machinery processing PVC – it achieves this using a fully mechanical scrubbing action.
It can be used for a wide variety of PVC extrusion processes, including pipe, sheet (standard and foam in both cases), and profile – as well as compounding.
PVC Purge is a PVC based, calcium zinc stabilised scrubbing purge whose results would not be believed unless seen. The example below is of a customer extruding flexible PVC on a 75 mm screw which had a formulation issue. Their degradation level was catastrophic but 25kg PVC Purge later and you can see these results yourself, they were ecstatic.
