Abstract: Two-component binder model systems composed of the non-polar polymer polypropylene and either non-polar paraffin wax (PW) or moderately polar stearic acid (SA) as low molecular weight components (LMWC) have been chosen in order to study the achievable weight loss (removable mass) of LMWCs during conventional thermal debinding in the lower temperature regime. Stainless steel 316L served as the powder material If has been found that the removable mass of SA is considerably lower than that of PW. This effect reflects the physical interaction of the low molecular weight components with the basic polymer. The influence of the debinding temperature and the sample thickness on the removable mass is discussed. The phenomena of removable mass influences the burnout cycle of powder injection moulded parts and attention has to be paid to this effect when devising a conventional thermal debinding treatment for a given binder.
