Investigation of the changes in melt flow indexes (MFI) and densities of polyamide 6 (PA6) and polyoxymethylene (POM) related with hydrolyzed powder coating waste amount

In this study, the changes in melt flow indexes and densities of polyamide 6 (pa6) and polyoxymethylene (pom) depending on the amount of added hydrolyzed powder coating waste, have been investigated. hydrolyzed electrostatic powder coating waste consist of a mixture of waste formed during the thermoplastic and thermoset electrostatic powder coating process. these wastes have been mixed with polyoxymethylene and polyamide separately with different proportions (10%, 20% and 30%) by weight, and the changes in melt flow indexes and densities of these mixtures have been analyzed at certain temperature and pressure. thus, the change of flow and densities of polyamide 6 (pa6) and the polyoxymethylene (pom) depending on the concentration of hydrolyzed powder coating waste have been determined and presented.
