Resumo(s)
In this study; Ground Tire Rubber (GTR) from scrap tires were blended with Polypropylene (PP) using injection moulding without any additional additives.
The effect of particle size and content was investigated by using 0.25mm and 1mm particles with 3 different level contents.
Testing and analysing the samples for shore hardness, wettability, mechanical and morphological properties. The former showed, the bigger the particle size the bigger are the gaps between the phases which is probably the cause for poor tensile performance reported.
Adding GTR to PP clearly enhanced the wettability property, the resultant mixture PP/GTR could be used in future works for achieving Design for Environment, Recycling, Manufacturing and Cost.
