COMPARAÇÃO ENTRE O POLIETILENO VERDE E O POLIETILENO PETROQUÍMICO: UM ESTUDO DAS CARACTERÍSTICAS FÍSICO-QUÍMICAS

Abstract

Esse trabalho objetivou a realização de uma revisão bibliográfica e a comparação do polietileno de origem verde e o polietileno de origem fóssil, utilizando o teste em câmara de envelhecimento forçado com luz UV. Os ensaios foram realizados com amostras de origem vegetal e fóssil, na 1ª etapa foram submetidas apenas à luz UV, logo em seguida o 2º experimento foi realizado com a luz ultravioleta juntamente à água destilada. Com o levantamento de dados, foi observado que no teste em câmara UV, as amostras verdes tiveram uma maior diminuição de massa, enquanto as amostras de origem regular obtiveram uma redução menor comparada à resina plástica. Já com a câmara UV e com o uso da água destilada, as amostras não apresentaram dados significativos, concluindo-se que com o uso da água destilada em conjunto com a câmara UV, houve resistência à degradação devido ao contato direto com meio aquoso.
