The SPE Library contains thousands of papers, presentations, journal briefs and recorded webinars from the best minds in the Plastics Industry. Spanning almost two decades, this collection of published research and development work in polymer science and plastics technology is a wealth of knowledge and information for anyone involved in plastics.
Exposure of plasticized polymers to natural ageing exhibits hardness and tensile-strength degradation, particularly in the presence of both nitrogen dioxide and ozone.
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.
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.
The rheology and morphology of uncompatibilized and reactively compatibilized blends of polytrimethylene terephthalate and ethylene propylene diene monomer correlate strongly.
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.
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.
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.
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.
Superimposed cyclic tension or shear stress increases time-dependent deformation, while constant stress accelerates accumulation of ratcheting strain in cyclic tension or shear loading.
The differing compatibilities of organoclay, thermotropic liquid crystalline polymer, and polyethylene produce a range of structural and flow behaviors in their blended forms.
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.
In this work, two different HDPEs were investigated from rheological as well as die drool phenomenon point of view. It has been revealed that long-chain branching and low polymer melt elasticity significantly reduce die drool phenomena at the die exit region.
