Influência das variáveis do processo de mistura na morfologia e propriedades finais de filmes tubulares de nanocompósitos de polietileno de alta densidade
(Universidade Federal de São Carlos, 2006-12-15)
Blown of films is one of the most important processes of polymers for packaging application. The final properties are strongly linked with the morphology developed during the processing. The relationship between process ...
Estudos e desenvolvimento de processos de pós condensação no estado sólido do PET reciclado
(Universidade Federal de São Carlos, 2003-12-04)
The increasing requirement of Ply(ethylene terephtalate) PET from the package market has made this available to the public discarded, quickly, since the technology of multi way package hasn t been possible due to high cost ...
Reciclagem química de PET proveniente de filtros industriais pós-consumo
(Universidade Federal de São Carlos, 2006-03-10)
The PET filter bag is used in the separation of the particulates materials of the gas produced in the aluminum industry. It had been submitted a chemical recycling. Almost industries make the disposal of these materials ...
Desenvolvimento de perfis extrudados de compósitos de polietileno de alta densidade com farinha de madeira
(Universidade Federal de São Carlos, 2009-12-17)
Polymer profiles extrusion shows some peculiarity due to the flow behavior of these materials during the processing. On the other hand, the profile die design and tooling has been more a result of professional s expertise ...
Desenvolvimento e caracterização de blendas PHBV/Ecoflex® e suas modificações com amidos
(Universidade Federal de São Carlos, 2008-05-30)
Plastics materials produced from petrochemicals are widely used due to
their versatility, mechanical properties and low cost, but they cause environmental
impact as a consequence of the accumulation of great amount of ...
Obtenção de nanocompósitos de poliamida 6 / argila nacional com diferentes agentes compatibilizantes
(Universidade Federal de São Carlos, 2005-09-01)
The formation of nanocomposites well exfoliated is dependent of several factors, like organic treatment with appropriate ammonium quaternary salts to promote adequate interaction between polymer and clay. The objective of ...
Estudo da tenacidade à fratura por meio do método do trabalho essencial de fratura (EWF) da blenda PBT/ABS, reforçada com fibra de vidro
(Universidade Federal de São Carlos, 2008-06-05)
High rubber content acrylonitrile-butadiene-styrene terpolymer (ABS) has been used to tough PBT. As a result, super tough PBT/ABS blends under notched Izod impact have been obtained. However, there has been a significant ...
Modificação do Poli(hidroxibutirato) PHB com nucleantes e com o copolímero (etileno-co-acetato de vinila) - EVA
(Universidade Federal de São Carlos, 2008-03-19)
In this work, we sought to modify PHB, processing it in the melted state, and to
evaluate the effect of the modifications on its mechanical properties and
biodegradation characteristics. The following systems were therefore ...
Preparação de argilas organofílicas para o desenvolvimento de nanocompósitos a partir de compostos de PVC plastificado
(Universidade Federal de São Carlos, 2009-12-15)
Nanocomposites of Plasticized PVC with organoclays have a large potential to improve the thermal resistance of PVC as well as its flame retardancy. However, a great problem in the production of PVC nanocomposites is the ...
