Influence of chemical nature, expansion ratio and cellular morphology on the fracture behaviour of flexible polyolefin-based foams assessed by the Essential Work of Fracture (EWF)

Abstract: Several commercial polyolefin-based flexible foams produced by extrusion foaming were characterized in terms of their cellular morphology and fracture behaviour using the concept of the Essential Work of Fracture (EWF), focusing on the influence of foam's chemical nature, expansion ratio and cellular structure on the values of the fracture parameters. Correction procedures were proposed in order to take into account the complexity of foams in the obtained fracture parameters, particularly a correction procedur… Show more

“…Foamed polymers are widely used in construction, vehicles, packaging, electric appliances, sports equipment, and so forth [1][2][3][4][5] due to lightweight, high strengthto-weight ratio, electrical insulation, and high impact strength. EVA is a copolymer of ethylene and vinyl acetate, which represents the hard segment and the soft segment.…”
