MACHINERY | ALTERNATIVE EXTRUDERS
Rigth: A Compeo 55 kneader extruder from Buss configured for PVC
compounding with a cascade/ two-stage set-up of
compounder and discharge unit
says Lloyd. “The CPeX design allows compound- ers to conduct laboratory-scale product develop- ment trials, extend product application portfolios, expedite time to market and reduce development costs. The CPeX is the only compact processor available that sup- ports both standard and CPXL rotor configurations for thorough development trials. It has fully integrated wiring and piping that is ‘connect and go’ and suitable for any industrial voltage.” One recent application involved joint
research with NatureWorks to compare the processing of Ingeo polylactide (PLA) compounds on the Farrel CPeX laboratory continuous mixer versus a twin-screw extruder. The project evaluated the effect of molecular weight loss in PLA while adding a talc mineral filler. It found that processing with the continuous mixer resulted in significantly better molecular weight retention — 95% molecular weight retention when using 50% filler and 88% retention when using 60% filler. Similar results have now been replicated utilising a production scale continuous mixer and these findings will be released in the near future, the company says.
Kneading technology The main application area for alternative com- pounders continues to be shear-sensitive com- pounds that require a high dispersive and distribu- tive mixing intensity, according to Buss. These have traditionally included highly filled polyolefin-based products such as HFFR, Sioplas, semicon and HV-XLPE cable compounds, as well as soft and hard PVC formulations for flooring, cables and medical, elastomers, thermosets such as EMC, and masterbatches and engineering plastics.
