Freeman Technology is pleased to announce the release of a new application note that demonstrates the value of powder rheology in identifying and quantifying minor differences in material batches that can influence process performance and ultimately impact product quality and productivity.
Titanium Dioxide has been used as a pigment and opacifier in a wide range of industries for many years, due to its bright white colour and high refractive index. However, despite such widespread use, processing Titanium Dioxide in its powdered form is often extremely challenging due to the powder’s high cohesivity. Special measures often need to be implemented when managing this material in operations such as dispensing from hoppers, feeding into unit operations and blending with other powders.
Identifying and quantifying which powder properties are conducive to efficient processing allows new formulations to be optimised without the significant cost of running samples through the process to assess suitability, making considerable savings in terms of time and raw materials, and minimising wastage due to out of specification products.
‘Assessing Batch-to-Batch Variability of Bulk Chemicals’ presents a study using the FT4 Powder Rheometer® to evaluate batches of titanium dioxide - a material used in a wide range of applications across various industries but widely acknowledged as being extremely challenging to manage and process.
