RT info:eu-repo/semantics/article T1 Foams with enhanced ductility and impact behavior based on polypropylene composites A1 Muñoz Pascual, Santiago A1 Sáiz Arroyo, Cristina A1 Vuluga, Zina A1 Corobea, Mihai Cosmin A1 Rodríguez Pérez, Miguel Ángel K1 Polypropylene K1 Polipropileno K1 Halloysite nanotubes K1 Nanotubos de haloisita K1 Foams K1 Espumas K1 Ductility K1 Ductilidad AB In this work, formulations based on composites of a linear polypropylene (L-PP), a long-chain branched polypropylene (LCB-PP), a polypropylene–graft–maleic anhydride (PP-MA), a styrene-ethylene-butylene-styrene copolymer (SEBS), glass fibers (GF), and halloysite nanotubes (HNT-QM) have been foamed by using the improved compression molding route (ICM), obtaining relative densities of about 0.62. The combination of the inclusion of elastomer and rigid phases with the use of the LCB-PP led to foams with a better cellular structure, an improved ductility, and considerable values of the elastic modulus. Consequently, the produced foams presented simultaneously an excellent impact performance and a high stiffness with respect to their corresponding solid counterparts.
