Size effect of recycled material to tensile properties of PC

Abstract

The aim of this research paper is to study the effect of particle size of recycled polymeric material to mechanical tensile properties. During grinding particles are formed which have a different size, shape and surface, from larger pieces to dust particles. During processing these particles melt at different rates depending on their size. For example they can cause material degradation or lack of melt homogeneity. Several recycled mixtures were prepared that had differed particle size after crushing. The recycled material is always the same as is the original material. The studied material was a Polycarbonate. Testing was performed using a tensile test. When comparing a virgin polycarbonate with recycled mixtures, the particle size of the recycled material affects some of the material parameters quite substantially, but it had no effect on some other properties. © (2014) Trans Tech Publications, Switzerland.
