Rheological studies

• Haake extrusion rheometer
  • The rheological behaviour of your polymer can be studied under realistic conditions with the Haake extrusion rheometer, equipped with several kinds of home-made devices, to control the moisture content of the chips, if needed. Simple apparent shear viscosity vs. apparent shear rate curves at your process temperature and conditions can be performed, but also master curves for rheological calculations are possible. Elongational viscosity can be measured, as well as the (Rheotens) melt strength curve. Small scale cast film and blown film devices are available. Also a very small-scale spinning device for 10filaments can be applied.
• Goettfert capillary rheometer
  • For small amounts of granulate a capillary rheometer is available, equipped with a dryer as a dosing device.
• Rheometrics controlled strain torsion rheometer
  • The molecular architecture of your polymer types, in terms of molecular weight and its distribution, tacticity (if monomer has a chiral centre) and branching, strongly affects its melt flow. Very often the rheology has proven to be extremely sensitive to changes in molecular structure.
  • This oscillating rheometer is not only a powerful tool in studying the above, but also in the determination of thixotropic or rheopectic behaviour of dispersions.
  • Temperature range -160 up to 300 °C.
• Melt Flow Rate (MFR)
