Krauss Maffei Extrusion of Munich Germany, specialist in plastics machinery, recently supplied a twin screw extruder to the Belgium research centre ‘Materia Nova’ for use on a research and development project into biodegradable plastics.

Polymers are one of Materia Nova’s main fields of research, together with surfaces and interfaces, with biotechnology, nanocomposites, surface treatment processes, such as coating and printing, and biopolymers.

The scientists will use the Krauss Maffei ZE A UTX twin screw extruder to research the production of biopolymers, particularly their processing to compounds. In polymerization, the ZE A 60 UTX twin screw extruder's output is between 30 and 60 kg/h, while in compounding output it can reach 300 kg/h.

Materia Nova chose the ZE A 60 UTX twin screw extruder as it provides a high level of flexibility for many diverse applications. A processing length of 56D ensures the long residence time essential for the polymerization of PLA and also for gentle incorporation of mineral or fibre fillers when used in compounding tasks. A side mounted feed unit ensures optimal metering of the fillers.

Two exchangeable screw sets allow for easy interchange between production over polymerization to compounding and visa versa. The metering units allow the feed of dryblend, pellets or liquids, and the system also has two pelletizers - an underwater and strand pelletizer.

Krauss Maffei is represented in Oceania by HBM Packaging & Plastics Technologies .
