초록
In recent, recycling of plastic material has became a major issue due to the landfills and environmental problem. This study investigated fluidity and hardness of thermoplastic vulcanizate(TPV), which is used for automobile component parts such as weather strip in order to replace ethylene propylene rubber (EPDM). So, using the spiral flow test mold, we conducted an experiment on fluidity and hardness of TPV according to injection molding conditions. As results of injection molding experiment, the recycled TPV's flow length was a little bit longer than virgin TPV and the hardness was decreased in case of using the recycled resin. Also, we investigated the morphology study by SEM photo.
