In Flow State
Ever wonder why you have to shake your bottle of ketchup or mustard before pouring? Or why, to get out of quicksand, you must move slowly? Or why you can run on the surface of a suspension of cornstarch in water, but you’d sink if you tried to walk on it? The common feature of all these conundrums a more
Malvern supports TU Clausthal in the characterization of drilling fluids
Researchers at The Institute of Petroleum Engineering at TU Clausthal in Germany are being supported by Malvern Instruments in new work to understand and optimize the performance of Enhanced Oil Recovery (EOR) fluids. The polymeric solutions used for EOR exemplify the fluids used in a range of drill more
Growing Freeman Technology establishes new US subsidiary
Building on a decade of successful business in North America, Freeman Technology announced that in January 2012 the company formally established a US subsidiary, Freeman Technology Inc.This new organisation will take on responsibility for sales, service and applications support for the ever growing more
Anton Paar’s MCR rheometers have opened more doors and created more testing possibilities than any other rheometer in the world. In keeping with this tradition, Anton Paar is now expanding the rheometer family with MCR 72 and MCR 92. With these new instruments your sample’s flow behavior, deformatio more
Anton Paar introduces the third generation of Modular Compact Rheometers. More versatile than ever, the current MCR rheometer series offers one thing first and foremost: An open range of possibilities. This is how Anton Paar defines future-proof rheometry: Whichever new application opens up, MCR rhe more
Designed entirely from the ground up, Kinexus redefines the rheometer. It enables users to spend less time learning how to interact with their system and more time investigating ways to characterize and enhance a material’s performance. Kinexus incorporates technological innovations in the most crit more
Making the Connection – Particle Size, Size Distribution and Rheology
A number of factors influence the rheology of a suspension, including particle size, particle size distribution, and the volume fraction of solids present more
This presentation reviews the test types available on a rotational rheometer for viscoelastic measurements, and assesses which are the most appropriate for sample types ranging from semisolids to low viscosity solutions and dispersions.
Rotational rheometers: comparison of test results made by parallel-plate and cone and plate geometries
The most widely used measuring systems for rotational rheometers are parallel-plate and cone and plate. This webinar reviews key measurement attributes for both geometries, and illustrates with data on non-Newtonian samples.
In this webinar we discuss the advantages of the Kinexus + series for your rheological measurement. Focus of the talk will be on the practical measurement results at low shears, how the unprecedented gap/axial capabilities of Kinexus can give you new insight to your sample properties, and the advant
Transient modeling of viscosity
Capillary and parallel plate rheological characterization was conducted for a low‐density polyethylene. In contrast with conventional rheological analysis, steady conditions were not assumed. Transient data, with time steps between 0.0001 and 0.2 s, were analyzed with a nonlinear, viscoelastic con more
Determination of the effect of pressure on viscosity at high shear rates by using an injection molding machine
ABSTRACT The effect of pressure on rheological behavior of polymer melts is surely a significant phenomenon for polymer processing, and its determination has been the object of several studies which highlighted the difficulties in performing accurate measurements. Even more important is the dete more
Effect of Viscosity Ratio of Two Immiscible Polymers on Morphology in Bicomponent Melt Spinning Fibers
Abstract Bicomponent fibers were melt spun to investigate the effect of individual component viscosity on the cross section morphology. Two couples were tested, polypropylene MFI 18 (PP18) with polyamide 6 (PA6) and, polypropylene MFI 25 (PP25) with polyamide 6 (PA6). Viscosity versus shear rate more
