Elastomer-rich thermoplastic polyolefin (ETPO) resin containing 70 wt% maleated styrene-ethylene-butadiene-styrene (SEBS-g-MA) and 30 wt% polypropylene and its nanocomposites filled with 1–5 wt% SiC nanoparticles () were fabricated using extrusion and injection molding techniques. The mechanical and thermal behaviors of ETPO and its nanocomposites were investigated. Tensile measurements showed that the additions lead to reductions in both tensile stiffness and strength of ETPO. However, Izod impact and EWF measurements indicated that the impact strength and fracture toughness of ETPO improve substantially with increasing content. This demonstrated that SiC nanoparticles toughen the ETPO blend effectively. Furthermore, additions were found to improve the thermal resistance of ETPO blend considerably.

The article discusses one of the modern areas of powder metallurgy – the technology of manufacturing shaped parts by the powder injection molding (PIM). For the powder-polymer mixture (feedstock) with a wax-polypropylene binder of the solvent-thermal type of removal by isobaric volume dilatometry, the dependence of PVT state parameters was studied. For each component of the polymer binder, the dependence of pressure on the temperature of phase transition was obtained. As a result of mathematical processing and analysis of PVT data for the feedstock of the studied type, a technological window of parameters has been determined that allows injection molding of «green parts» with minimal volume shrinkage. The results of a comparative analysis of the compaction of feedstock with a polymer binder catalytic and solution-thermal type of removal are presented.
