Abstract Scope The particular challenges related to the use of titanium and its alloy processed by MIM are its high reactivity and sensitivity towards contamination. In a typical MIM process, selections of appropriate binder and later removal have demonstrated to be crucial in reducing the contamination problem. The aim of this paper focuses on the development of a catalytic binder system based on polyacetal for Ti-MIM. An inherent characteristic of this catalytic binder system is their low debinding temperature at approximately 120-150 C, which is below the temperature where impurities uptakes initiate (~ 260 C). In addition, the effectiveness of employing organic acid as a potential green catalyst for the removal of polyacetal binder is reported.
