REPROCESSING OF STYRENE ACRYLONITRILE AND THE INFLUENCE OF THE PARTICLE SIZE ON TENSILE PROPERTIES

Abstract

The purpose of this work is to determine the influence of the reprocessed polymer on tensile properties. Tested samples were obtained using the injection molding technology from the industrial unpolluted waste, which is the same material as the virgin styrene acrylonitrile (SAN). The waste was milled for further reprocessing and a mixture of different particles was obtained. This mixture was sifted to fraction differ by particle sizes. These mixtures were characterized by tensile testing at the ambient temperature. It was found that mixtures with small particles influenced the non-sifted milled mixture even though these particles contain only a small amount.
