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 ...
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 ...
Desenvolvimento e caracterização de blendas e de compostos empregando polímeros biodegradáveis
(Universidade Federal de São Carlos, 2004-10-25)
This work presents theoretical information and experimental data on the behavior of biodegradable polymers and blends of biodegradable PHB polymer with copolyesters that are also biodegradable. Binary mixtures were made ...
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 ...
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 ...
Processamento, caracterização e determinação do perfil de polarização do Poli(fluoreto de vinilideno)
(Universidade Federal de São Carlos, 2009-03-25)
This work characterized the ferroelectric polarization of the β-PVDF differentiating the individual contributions of the orientation and the crystalline phases in the remanent polarization of the PVDF. Those contributions ...
Influência dos parâmetros de Processamento e da composição na morfologia de resinas ABS.
(Universidade Federal de São Carlos, 2004-08-24)
The present work is about the influence of processing parameter and composition on the morphology of acrylonitrile-butadiene-styrene (ABS)resins. The ABS grades chosen are commercial products with high rubber content, i. ...
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 ...
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 ...
Monitoramento in-line da formação de nanocompósitos PP/MMT via intercalação no estado fundido
(Universidade Federal de São Carlos, 2008-08-04)
The aim of this work is to monitor in-line, using an optical detector fitted at the extruder die exit, the formation of PP/MMT nanocomposites during polymer melt compounding. The intensity of the detector´s signal is ...
