Resumo
In the last years, the research on material recycling has being steadly growing in the entire world. In Brazil, this kind of
research is growing gradually, however recycling is still not part of Brazilian´s society, as generally occurs in developed
countries. The physical process of recovering of several types of polymers such as rubber, with high energy
(electromagnetic waves - microwaves) is the subject of researches at the CQMA/IPEN and Poli/USP. The object of this
present work was to evaluate the efficiency of this method in order to recover butyl bromine rubber used in
pharmaceutical products, aiming to return it as an active load instead of inert load. This process of devulcanization
involves exposing rubber materials to microwave energy under controlled conditions: frequency - 2450MHz, variable
power output - 1.0kW to 3.0kW, temperature of the samples and irradiation time. These conditions theoretically break
sulphur bonds and produce a rubber material that can be used in raw rubber compounds. The samples were analyzed by
several characterization techniques.
