Abstract

Polypropylene is one of the most used materials in the world because of its easy processability and good mechanical properties under different applications. As a result, a lot of polypropylene waste is being generated and recycling is important. The problem with recycling polypropylene is the changing in the properties when compared to virgin polypropylene. Processability parameters and mechanical properties of traction and impact can be changed after recycling this material, affecting companies in the polymer transformation sector. Thus, this work aims to obtain an empirical equation for the correction of the melt flow index of virgin and recycled polypropylene mixtures and also conducts a study on the mechanical properties of the mixtures comparing them with those of virgin polypropylene. The empirical equation found shows a linear relationship between the melt flow index of the mixture and the percentage amount of virgin polypropylene. From the mechanical properties, it was observed that the stiffness of the mixtures is similar to that of virgin polypropylene, however the energy absorbed under impact is considerably lower, compromising the use of recycled polypropylene for such application.

Summary

Introduction

As per the compliance and regulations of: Luiz Gustavo Barbosa α, Cassiano Rodrigo Dalberto σ & Edson Luiz Francesquetti ρ. Despite the use of plastics in general, more is important.The problem with recycling polypropylene is the changing in the properties when compared to virgin polypropylene. Processability parameters and mechanical the polymers, to exhibit a decrease in the generation of waste, their discard, as well of other properties of traction and impact can be changed after consumable materials, contributes to the recycling this material, affecting companies in the polymer production of urban waste and for the waste in the Global Journal of Researches in Engineering ( J ) Volume XxX Issue V Version I transformation sector. PP has Polymeric materials are an important group of the materials engineering because their easy production and wide range of applications This group includes materials such as plastics and rubbers ranging from low density liquids to rigid solids [1]. This production is expected to double again within 20 years, and by the year 2050 it has practically quadruple [2]
