A defined particle profile can make a filler enquiry more precise. This precipitated barium sulfate powder has body particle parameters of D50 0.7 μm and D97 1.95 μm, with a selectable whiteness range of 98.5–99%. Paint, masterbatch filler and powder-coating filler are named directions.
Compare the median and upper particle measurements
Request the report and methods behind the D50 and D97 values. Keep crystal dimensions separate until their relationship to the particle distribution is defined. A single crystal description should not become an assumed maximum for the powder used in a formulation.
Bring the oxide analysis into material selection
The stated oxide profile includes CaO, Fe2O3, MgO, SiO2, BaO and Na2O values. Ask which constituent limits matter to the intended project and obtain current analysis on a reconciled assay basis. Moisture is stated as below 0.30%, with pH of 7±0.5, each requiring its own measurement method.
Define the filler role in paint or masterbatch
Identify the binder or polymer system and the properties that will decide trial acceptance. Evaluate the selected sample through that actual process. Particle measurements and a white appearance do not establish a universal addition rate, dispersion result or finished-product improvement.
Match documents to the selected whiteness option
Specify the required whiteness range and measurement basis in the enquiry. Request any restricted-substance documentation required by procurement and confirm its relevance to the sample. Keep the technical reports with the material used in the controlled comparison before deciding on acceptance.
