Description
Versatile
The new LCR7000 Series Capillary Rheometers offer many new features and will meet the demands of a 24-hour-a-day shop floor operation while maintaining the highest possible level of accuracy, repeatability and sensitivity. The LCR series rheometers are versatile and easy to use yet they offer the most sophisticated materials characterization, data analysis, and reporting capabilities. The LCR series can be used with a standard load cell and a barrel mounted pressure transducer.
Sophisticated Software
LAB KARS (“Kayeness Advanced Rheology Software”) is the most powerful and easy to use rheological Windows™-based software package available. Just a few of its easily useable features include: Bagley and Rabinowitsch Corrections plus power law, Carreau, Modified Cross and polynomial viscosity models. With this software users can merge multiple data files from shear stress, shear rate, or thermal stability tests. The resident KARS SQC module can be used to quickly identify viscosity variations in different lots of material. A program for the correlation of melt viscosity to intrinsic viscosity, for PET and Nylon, is also included.
Real-Time Display
In addition to all of its other powerful features LAB KARS for Windows™ provides a real time display of force or pressure versus time as a test progresses. This feature allows the operator to identify the steady state flow condition for the material. In addition, the presence of contamination, unmelted resin, or bubbles in the material may be identified from spikes in the force versus time curve.

Effects of Viscoelastic Properties of Polymer Melts on the Entrance Flow PatternAnalyzing elastic properties and predicting flow instability of viscoelastic polymers is important for designing dies and flow systems in an extrusion process simulation or quality/process control purposes. This is even more essential for the processes that are involved with stretching of polymer melt such as film/sheet extrusion or blown film extrusion

The controlling factor in all polymer conversion processes is the materials rheological behavior. Check out this recent white paper in conjunction with EMC Electrical Mechanical Controls and Applied Polymer Technologies (APT) and learn how rheological measurements can detect the most discrete changes in structural properties.
Detecting Polymers in Material Products
It can be very difficult, if not impossible, to achieve complete indentification of most polymer products. However, in most cases, this is usually not needed; what is needed is the separation, or identification, of numerous molding materials whose identity has been lost, or an indication of the type of material used to create a component.
Key Violation in LabKars Software
The following instructions will resolve the key violation error that appears in Labkars software, which is used to control our LCR7000 series capillary rheometers
What is the advantage of using a pressure transducers in the Dynisco LCR?
The Pressure transducer will allow the end user to monitor pressure in the capillary. High shear rate flow testing is commonly carried out by forcing the melted plastic material through a die of specified size, using piston at a known piston speed and material temperature. The pressure, or force, required to maintain the specified flow rate is measured. The piston speed is then changed and the new force or pressure generated at this speed, is measured and recorded. For each piston speed a force or pressure is recorded. Knowing the barrel dimensions and the piston speed, the volumetric flow rate through the die can be calculated. In turn the shear stress and the shear rate are calculated and used to construct flow curves.
