Compositos de polietileno verde e argila vermiculita foram desenvolvidos por meio da tecnica de intercalacao por fusao com o objetivo de investigar seu potencial uso como material de construcao. Os compositos foram processados em uma extrusora monorosca e moldados em uma termoprensa hidraulica. Para este trabalho, foram analisadas a resistencia a propagacao de chamas e os efeitos do envelhecimento natural do polietileno verde e seus compositos. Amostras foram expostas a um ensaio de degradacao a...

Summary Growing demands for the use of biodegradable polymer films in food packaging have led to studies on several sources of non-conventional starches. Corn starch (CS), is the most investigated starch source for food packaging due to its abundance and stability under processing and manufacturing conditions. Other sources of starch such as rice, potatoes and cassava have also been investigated and, more recently, babassu mesocarp starch (BMS), native to Northeastern Brazil, has been explored f...

Abstract It is well known that the inadequate disposal of polymeric materials causes significant environmental problems. Recycling and the use of biodegradable polymers are among the methods used to minimize these problems. However, the low mechanical performance of the majority of biodegradable polymers hinders the direct substitution of synthetic polymers, such as polyethylene (PE), polypropylene (PP) and polystyrene (PS), by biodegradable ones. Blending synthetic and biodegradable polymers is...
