Effect of Recycled Particle Size to Micro-Hardness Properties of Styrene Acrylonitrile

The aim of this research paper is to study the effect of particle size of recycled material on the micro harness. Valuation of recycled material effect takes place in several mixtures of materials. These mixtures differ in particle size, which are made during grinding of plastic waste, from large particles similar to the original material to dust particles. The recycled material is always the same as is the original material. Tested material is styrene acrylonitrile SAN. Testing is performed at ambient temperature of 23°C. After the first recycling there is a change of hardness; which decrease mostly in mixture with the smallest particles.
