Researching production of biopolymers
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. Scientists in
KraussMaffei Berstorff engineered the extruder to meet Materia Nova’s specifications. With its modular engineering, characteristic of all ZE machines, the extruder provides the very highest level of flexibility for many diverse applications. A processing length of 56D ensures the long residence time essential for the polymerization of PLA, for example, and also for gentle incorporation of mineral, or fiber, fillers when used in compounding tasks. A side-mounted feed unit ensures optimal metering of the fillers.
Two, easily exchangeable screw sets make it a simple matter to swap production over from polymerization to compounding and vice versa.
The metering units can feed dryblend, pellets or liquids. The system also includes two pelletizers; for maximum flexibility, Materia Nova ordered both an underwater pelletizer and a strand pelletizer. The latter can be combined with an air-cooled metal grid-type conveyor belt.
Luc Langer, Materia Nova CEO, explained the decision to invest in the KraussMaffei Berstorff machine: “Apart from the expertise that went into the engineering of the pilot system, which impressed us from the start with its tremendous flexibility, we valued the outstanding support we got from KraussMaffei Berstorff any time we had a question.”
