Atlas MF12 Melt Flow Indexer is a simple, yet sophisticated extrusion plastometer to determine the flow rate of thermoplastics, check incoming materials and characterize new polymers.
The melt flow rate (MFI, g/10 min) was monitored according to ISO 1133 (2005) at a temperature of 250[degrees]C, and load of 2.16 kg on a Zwick plastometer 4100 instrument, based on the mass-measurement method.
The Cflow is an extrusion plastometer from Zwick which has been added alongside the Mflow and Aflow instruments (British Plastics & Rubber, February 2010, page 7).
The Aflow extrusion plastometer uses cutting-edge force, instead of the usual weights, to control stepless adjustment of test loads up to 50 kg and deliver faster, more reliable melt index determination, the company says, and the roboTest H robotic testing system delivers automated Charpy or Izod impact tests on room-temperature and cooled plastics specimens with "safe, reliable transport of the specimen to the support, together with automatic specimen alignment and hammer release."

The Zwick Roell Group, Ulm, Germany, has introduced a new extrusion plastometer to its Xflow series, the "Aflow," which delivers rapid, convenient determination of melt index values, the company says.
