The glass‐transition temperature (Tg) is a fundamental property of all organic binders, It is illustrated with polyethylene glycol (PEG)‐plasticized polyvinyl alcohol (PVA) binder systems that densification is enhanced when the binder Tg, is below the pressing temperature. This is a result of the increased deformability of the binder system and the decrease in the granule strength. Because of the reduction in the binder film strength with increasing PEG content, increasing the PEG content to lower the binder Tg, results in reductions in the compact green strength.
