Each episode is dedicated to a specific topic and explains clearly how our methods work, what makes them special and how they can be used optimally.
Dive into our world of Rheology and improve your knowledge from the comfort of your screen - whenever and wherever you want.
Sustainable quality control in the plastics industry
Viscosity measurement is essential for your quality assurance in polymer production and processing, as it describes the flow behavior of your material under real conditions. Precise measurement ensures your product quality, reduces rejects and optimizes processes. For more efficiency and sustainability. Important methods include solvent viscosity to determine the molecular weight, the Melt Flow Index (MFI) to measure flowability and melt viscosity, which measures the material's resistance to external stresses.
Shark Skin vs. Normal Stress Die
Flow instabilities might appear when measuring plastics, elastomers or food products. You can measure these either with the Shark Skin measuring head or with the Normal Stress Die.
The video shows you the exact differences between the two and why the Normal Stress Die provides more detailed data.
Highest precision, minimal automation
The instrument enables both MFR and MVR measurement in accordance with ISO 1133 and ASTM D1238 in methods A, B and C. In addition, the melt density can be reliably measured. A high-resolution displacement transducer with an accuracy of 0.003 mm per pulse ensures precise measurement results. It is conveniently operated via a single multifunction button. Both the parameter menu and the measurement results can be displayed and controlled on different PCs via VNC.
Rubber Capillary Rheometer RCR
A Capillary Rheometer is used to determine the flow and vulcanization behaviour of rubber compounds in a short test under processing conditions. The measurement of duromers/thermosets is also possible as an option.
The RCR is optimized for the shortest possible measuring time and simple operation in order to deliver results very quickly, especially in quality control. A typical measurement takes approx. 2-5 minutes.
Melt Flow Index and Elongational Viscosity
The D-MELT enables the determination of Melt Flow Index and Elongational Viscosity in one measurement. This combination is particularly interesting as a quick test in the incoming goods inspection for processing polymers. The short test time and easy handling is an essential advantage why both material manufacturers and processors use this instrument in the quality control of extrusion materials.
