Gneuss: The MRS Extrusion System - Unique Polymer Devolatilising Technology

At the FAKUMA 2009 Gneuss (www.gneuss.com) will show a further highlight: a demonstration model of the new type of extruder developed by Gneuss. Since its introduction in 2007, this extruder has set new standards with regard to the degassing or devolatilisation of polymers.

The patented MRS extruder is based on a multiple screw system consisting of a single screw drum with satellite screws provides an extremely large and fast changing melt surface for unmatched degassing or devolatilising performance. The MRS extruder ensures the processing of undried PET flakes or chip/pellets to sheet, fibres or strapping tape with a simple vacuum of only 20 - 40 mbar.

This system also permits the extremely efficient extraction of solvents or other problematic volatiles during plastics manufacture or processing.

In addition to the excellent degassing or devolatilising properties, the simple and rugged design of the MRS makes it the ideal machine for the processing of heavily contaminated materials. In combination with the Gneuss Online Viscometer, continuous monitoring and control of the melt viscosity is made possible.
