Influence of Recycled Particle Size to Tensile Properties of Polyamide 6

摘要

The aim of this research is to show influence of particle size of recycled polymeric material to mechanical tensile properties. While grinding, the particles with various sizes are formed, from larger pieces to dust particles. This size variation can cause problems during subsequent processing. These particles of different sizes have distinct melting rate. That can cause an inhomogeneity of a melt and diverse structure of a solidified polymer. Several recycled mixtures with varied particle size after crushing were prepared. Tested polymer was polyamide 6 and the tests were performed at ambient temperature.
