Abstract in Portuguese
O desenvolvimento de novos produtos e novas tecnologias tem se tornado um fator predominante no contexto da competitividade, onde se observa uma constante busca pela melhoria da qualidade e baixo custo. Trabalhos recentes mostraram o desenvolvimento de novos materiais dielétricos, baseados em resinas poliuretanas derivadas do óleo da mamona (ricinus communis). Hoje suas principais aplicações encontram-se nas áreas médicas. Pesquisadores brasileiros podem sintetizar tais materiais, assim, este trabalho visa caracterizá-lo quanto à suas propriedades elétricas. Um grande número de ensaios foram realizados, obtendo-se resultados que sugerem perspectivas promissoras para sua utilização como isolantes sólidos. A metodologia de preparo das amostras das resinas adequadas aos ensaios é também apresentada

Abstract in English
The development of new products and new technologies have become a predominant factor for competitiveness, in which it is observed a constant search for the quality improvement and low cost. Recent works show the development of new dielectric materiais based on poliurethane resins derived from castor oil (ricinus communis). Today, the main applications of such resins are found in the medical areas. Brazilian researchers can synthesize those materials, thus, this work aims at characterizing the materiais according to their electric properties. A number of tests were executed, and the obtained results suggest promising perspectives for their use as solid insulatings. The methodology for preparing the adequate resin samples for the tests is aiso presented.
