Study of mixing reprocessed polycarbonate on charpy impact properties at increased and decreased temperature

Abstract

The feasibility of reprocessing has been studied as a possible alternative to polycarbonate recycling. The reprocessed polycarbonate was mixed in different proportions with the virgin polycarbonate, and several mixtures were made which were subjected to measurement. The ascertained properties were compared with the virgin material. Polymeric waste from polycarbonate was grinded. The prepared mixtures were subjected to Charpy Impact Properties. This measurement was carried out at two different temperatures, a low temperature minus 23 °C and an elevated temperature of 60 °C. These two temperatures were selected because polycarbonate products are often used in the automotive industry when such temperatures may occur. At low temperature, the results show that the mixtures show less influence on the reprocessed material for the measured properties. At higher temperatures, the effect of reprocessing can be observed, especially the impact of Charpy notch strength. © 2018, North Atlantic University Union. All rights reserved.
