Dispersão seletiva de argila montmorilonita em blendas poliméricas de PA6/ABS
(Universidade Federal de São Carlos, 2009-08-25)
For some applications toughening of polyamide is important. This can be accomplished through the addition of an elastomeric phase to the polyamide matrix with the drawback of a reduction in the stiffness and strength of ...
Caracterização físico-química de PET ramificado e de suas blendas com PET reciclado
(Universidade Federal de São Carlos, 2004-05-10)
The growing concern with the solid residues management, observed in the last decade, due to its huge amount and impact, has motivated the search for recycling processes, where these residues can be reprocessed to generate ...
Grau de cisão de cadeia na degradação termomecânica de polímeros sob multiplas extrusões
(Universidade Federal de São Carlos, 2004-09-14)
One of the ways to follow the polymer degradation has been to calculate the average number of chain scissions (ns) that occurred during its
thermomechanical history. The average can be extended for each molecular weight ...
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 ...
Avaliação de sistema estabilizante para cobertura de cabos aéreos em XLPE.
(Universidade Federal de São Carlos, 2005-08-03)
Overhead energy lines with covered conductors are increasingly used in the 15 kV distribution systems in Brazil. The advantages are, among others, reduced distances between phases, no disruptions due to conductor ...
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 ...
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 ...
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 ...
