SPE Library content related to rheology
Effects of pressure and gases on viscosity of molten plastics
John Dealy , Hee Eon Park, December 2010
A high-pressure sliding-plate rheometer provides an attractive alternative to conventional instruments for measuring the impact of pressure and dissolved gases on polymer behavior.
Rheological structure of silver nitrate micro-emulsions
Edna C. de la Cruz, Jose C. Ortiz, Hened Saade, Raul G. Lopez, December 2010
Bicontinuous aqueous micro-emulsions exhibiting Newtonian behavior and low viscosity are suitable for silver-nanoparticle synthesis.
Nanocomposite dispersions based on cellulose whiskers and acrylic co-polymer
Ayman Ben Mabrouk, Sami Boufi, December 2010
Addition of methacryloxypropyl triethoxysilane stabilizes the dispersion and favors anchoring of the whiskers onto polymer particles.
Using a torque rheometer to characterize flow in poly(vinyl chloride) composites
Gulsen Albayrak Ari, November 2010
An instrument that is basically a batch mixer provides valuable data regarding the processability of polymer micro- and nanomaterials, and is also a useful tool in quality control and product development.
Mechanical characterization of hydrogel
Allan D. Rogalsky, H. J. Kwon, October 2010
Digital image correlation is a viable approach to noncontact deformation sensing.
Reactive compatibilization of polymer blends
Sabu Thomas, Indose Aravind, October 2010
The rheology and morphology of uncompatibilized and reactively compatibilized blends of polytrimethylene terephthalate and ethylene propylene diene monomer correlate strongly.
Compatibilizers improve exfoliation in polymer-clay nanocomposites
Saul Sanchez-Valdes , Luis Francisco Ramos-deValle, August 2010
Melt viscosity, measured by capillary rheometry, indicates the degree that exfoliation is improved by adding maleated polyethylene compatibilizers to polyethylene-nanoclay composites.
Predicting flow and temperature effects on polymer crystallization
Patrice Chantrenne, M'hamed Boutaous, Rabie El Otmani, Matthieu Zinet, July 2010
Simulating crystalline microstructure development under various thermal and mechanical conditions provides an essential step towards determining the final properties of injected parts.
Stronger high-density polyethylene
Xiaolei Chen , Lumin Wang, July 2010
Differential-scanning-calorimetry measurements show that nanocomposites containing barium sulfate have a more perfect crystalline phase.
More efficient manufacture of controlled-rheology polypropylene
Santanu Dutta , Amit Rai, July 2010
Polymer formation of a certain molecular weight can be predicted with careful control of reaction conditions.
Nanotalc improves properties of polyamide-6 binary and ternary nanocomposites
Prasath Balamurugan , S. N. Maiti, July 2010
Nanotalc is more easily exfoliated than nanoclay through melt blending and forms extended, networklike structures and improved tensile strength, modulus, and flow in polyamide-6.
Phase coalescence impacts rheology and birefringence of polymer blends
Jinhai Yang , Qibo Jiang, James L. White, July 2010
A new phase-morphology development explains significant viscosity and birefringence drops following melt processing.
Effect of fountain flows on injection-molding-induced morphology
Yasuhiko Otsuki, Yutaka Kobayashi, Toshitaka Kanai, June 2010
In injection molding of polypropylene, extensional deformation at the advancing flow front causes high birefringence near the surface.
Thermoforming poly(methyl methacrylate) transparencies
Luc Chevalier, Pierre Gilormini, Gilles Regnier, June 2010
Numerical simulations enable prediction of the properties of polymer transparencies that are thermoformed near their relevant glass-transition temperature.
Viscoelasticity, tackiness, and extrusion flow of block copolymers
Maria Eugenia Munoz, Mercedes Fernandez, Alfonso Arevalillo, Pedro A. Santamaria, May 2010
The dominant rubbery state in high-molecular-weight thermoplastic elastomers leads to a lack of adhesion and a plug flow.
Interaction of normal and shear stresses in an epoxy polymer
Zihui Xia, May 2010
Superimposed cyclic tension or shear stress increases time-dependent deformation, while constant stress accelerates accumulation of ratcheting strain in cyclic tension or shear loading.
Blending sequence effects on rheological properties of ternary composites
Ping Gao, Youhong Tang, May 2010
The differing compatibilities of organoclay, thermotropic liquid crystalline polymer, and polyethylene produce a range of structural and flow behaviors in their blended forms.
Hossein Hosseini , Boris V. Berdyshev , Ekaterina M. Kromskaya, May 2010
Plug-assist thermoforming is a well known technique in polymer processing due to its interesting features. The dynamic value of driving-force for the stretching process is determined based on equilibrium equation. This amount of force is required for applying to a plug in order to stretch a sheet. It is used for calculation of the required theoretical work, and power of a plug-assist thermoforming process. By using a non-linear viscoelastic rheological model in the proposed mathematical model, its validity was examined by performing experimental tests on ABS sheets.
T. Beiss, C. Dallner, E. Schmachtenberg, May 2010
With the rapid increase in the market for recycled polyethylene from various sources, there is an urgent need to quantify the performance of these materials. Blends of recycled high density polyethylene (HDPE) were prepared to obtain specific mechanical properties and MFI. The results show that the MFIs had significant effect on the rheological, mechanical and phase morphology characteristics of the various blends.
Walter Michaeli, Micha Scharf, May 2010
Polyethylene/montmorillonite nanocomposites based on LDPE, HDPE and LLDPE of similar rheological properties were prepared and mechanically tested in tension mode. It was shown that nanocomposites based on LLDPE exhibit a very peculiar behavior, with a significant improvement in toughness (elongation at break). The microstructural features of the various nanocomposites were investigated through scanning and/or transmission electron microscopy. Based on those observations, an explanation for the deformation and fracture mechanisms in LLDPE/montmorillonite nanocomposites was proposed.
