Microcellular injection moulding: A comparison between MuCell process and the novel micro-foaming technology IQ Foam

摘要

The present work aims to compare two different injection moulding foaming technologies, the already known MuCell (R) process and the new emerged technology IQ Foam (R), as well as the cell structure and mechanical behavior of the obtained components. Glass fiber reinforced-polypropylene ( > PP GF <) was employed to produce rectangular plates at solid and foamed conditions by using MuCell (R) and IQ Foam (R) processes combined with the complementary Core Back expansion molding technology, and the material structure as well as the tensile, flexural and impact properties were studied.
