Processing chlorinated polyvinyl chloride (CPVC) compounds can present various issues because of their thermal instability characteristics. American Maplan has now made available a new screw design that provides a typical reduction of melt temperature of up to 15-20F, while providing superior plastification, for CPVC pipe extrusion.

A reduction of melt temperature extends the reaction or decomposition time significantly. Typically, reductions of melt temperature of 15-20F can double the decomposition time of CPVC compounds.

In addition, the use of this screw geometry typically doubles the time between purging and shut downs for cleaning.
