    2018-5-18 · The temperature of mixing is dependent on the viscosity of the feedstock and the thermal stability of the components used in the binder system. The viscosity of the feedstock determines the shear stress generated during compounding which in turn determines how well the powder agglomerates are broken and the individual particles are dispersed.
