Resumo
Plastics have been replacing other traditional materials such as wood,
metal and glass over the past decades due to its versatility in properties, processability,
and cost. Polypropylene can be highlighted as one of the main thermoplastics
used in industry since it presents properties suitable for various applications, combining
density, cost, availability, and ease of molding. By considering the mechanical
recycling of post-consumer or post-industrial material, difficulty in flowability is
observed, which demands modification to promote processability. This work used
the traditional solution for flow modification (peroxide) and elastomeric modifier
to evaluate the impact of these additives on the mechanical and flow properties of
recycled polypropylene by tensile strength, melt index and spiral flow analyses.
Although the modified sample with organic peroxide had a higher melt flow index,
the mechanical resistance was lower than the elastomeric modifier, which showed
good performance in the material flow during processing according to spiral flow
analysis.
