Mechanical Behaviour of High Density Polyethylene Based Foams

摘要：

This paper presents the mechanical properties of a collection of high dcnsity Polyethylene based foams. The produced materials are characterised by a reduction in density up to 60%, an excellent surface quality, cell sizes in the microcellular range (around 50 microns) and a multi-structured cellular structure (cranial structure) with dense skin and foamed core. The mechanical properties of these materials showed linear relationships between Youngs modulus and density for densities above 0.7 g/cm3. In addition, variations in the cell size did not influence the elastic properties.
