Avaliação do efeito de um óleo parafínico sobre o comportamento físico-químico de tubulações de polietileno de alta densidade

[摘要] The effects caused by a paraphinic oil on the physicochemical behavior of high-density polyehtylene pipes were investigated, as a function of time and temperature. These effects were evaluated by thermogravimetric and gravimetric analysis and by FTIR. The
