1. Estrategia para la optimización de un compuesto de caucho con aceite de soja utilizando diseños de experimentos
ABSTRACT When a rubber component is made, is necessary to start from a “rubber compound” which may be composed of one or more polymers and various additives or fillers. The development of an elastomer mixture to produce a compound with a specific end-use is complicated in the field of rubber technology. Therefore, the successful development of a compound

2. Toughening of polystyrene using styrene-butadiene rubber (SBRr) waste from the shoe industry
Abstract The vulcanized rubber waste from the shoe industry causes environmental damage when it is incinerated or inappropriately discarded, turning this into a problem of major concern. Therefore, this study had as the main objective the Polystyrene (PS) toughening using different contents of white vulcanized styrene-butadiene rubber (SBRr) waste produced i

4. Avaliação da influência de diferentes óleos extensores com baixo teor de policíclicos aromáticos nas propriedades da borracha à base butadieno e estireno (SBR) / Evaluation of the influence of different extender oils with low content of polycyclic aromatic on the properties of butadiene-styrene based rubber (SBR)
O óleo extensor normalmente empregado em copolímeros à base de butadieno e estireno ( borracha SBR) da série 1712 é o extrato aromático (DAE). Nesta Dissertação, esse óleo foi substituído por óleos com baixos teores de policíclicos aromáticos em formulações de SBR. Esta substituição se deu em atendimento a Regulamentação REACH (EC No1907/2

5. Evaluation of the influence of the polymer-filler interaction on compounds based on epoxidized elastomeric matrix and precipitated silica
The introduction of epoxy groups into the main chain of elastomers has emerged as a promising alternative, considering the monitoring of polymer-filler interaction leading to changes in the properties of vulcanizates. The epoxidation reaction (in situ) was chosen to modify elastomers, such as polybutadiene (BR) and copolymer of styrenebutadiene- rubber (SBR)

6. The use of styrene-butadiene rubber waste as a potential filler in nitrile rubber: order of addition and size of waste particles
Styrene-butadiene rubber (SBR) has large applications in the shoe industry, especially as expanded sheets used to produce insoles and inner soles. According to TG analysis, the rubber content in SBR residues (SBR-r) was found to be around 26-wt%. Based on that data, a cost-effective technique for the reuse of SBR-r in Nitrile rubber (NBR) was developed. Late

7. Desempenho físico-químico e mecânico de concreto de cimento Portland com borracha de estireno-butadieno reciclada de pneus
Physicochemical and mechanical techniques were carried out to characterize three concrete tyre-rubber waste dosages such as 5, 10 and 15%, w/w. The elastomeric material was identified as styrene-butadiene rubber (SBR). It was observed that the growing SBR content in the mixture decreased the concrete performance. The best results were presented by 5% w/w tyr

8. Obtenção e caracterização de artefatos produzidos com resíduos elastoméricos vulcanizados
The aim of this study was to incorporate styrene-butadiene rubber (SBR) industrial scraps into a base formulation of identical composition used in the fabrication process of extruded profiles. Technical and environmental performance of the developed composites was evaluated. The scraps were collected and ground under ambient conditions. The powder obtained,

9. Devulcanization of styrenebutadiene (SBR) waste tire by controlled oxidation
Neste trabalho é descrita a desvulcanização da borracha SBR (Styrene Butadiene Rubber) via oxidação controlada com ácido nítrico. Análises por IV, RMN de ¹H e 13C, CHN, TG, GPC e experimentos de DTP-EM (Decomposição a Temperatura Programada -Espectrometria de Massas) sugerem que o ácido nítrico promove dois processos: (i) a desvulcanização por

10. Estudo estatistico de parametros do processamento de borracha SBR para banda de rodagem de pneumaticos
In the present work, the processing of styrene-butadiene rubber was studied. The studies were on the material for the part of tire in contact with the ground. The rubber components mixing in a banbury type internal mixer, and material vulcanization in a heated press, were studied by factorial design method. The influence of rotation speed, inner pressure and
