Molding CPVC

Molding CPVC

Molding CPVC

(OP)
I have molded a lot of CPVC, but I haven't worked with it since about 1990. I found molding it to be challenging, requiring meticulous attention to processing and screw geometry selection.
A client has been told by a supplier that changes have been made in some CPVC formulations since then that make them easier to process.  Do any of the forum members have experience with CPVC
that would enable them to comment on changes in processing CPVC
over the past two decades?

Thank you

RE: Molding CPVC

(OP)
Thank you Mike: I share your skepticism. I have found references in my notes from 30 years ago that claimed that CPVC was "now much easier to process."  I always thought that processability could be improved only by reducing molecular weight or using additives that could compromise performance.  I was wondering if anyone was aware of a breakthrough in CPVC technology that eliminated trade-offs between processability and performance.
