Effects of Viscoelastic Properties of Polymer Melts on the Entrance Flow Pattern
Analyzing 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

Tech Notes
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
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.
