A talc comparison should distinguish mineral composition, particle measurement and the colour required in the finished product. XM-TA823 is talcum powder identified for coating and plastic evaluation. Its stated particle size is 15 μm, with moisture no greater than 0.5%.
Clarify what the 15 μm measurement describes
Ask which particle statistic and preparation method were used. The stated size does not identify a D50 or a complete distribution. Compare samples through the same measurement procedure before setting a fineness acceptance criterion for a coating or plastic compound.
Use the oxide profile as a composition reference
The stated composition includes SiO2 at 61%, MgO at 31%, Al2O3 at 1.0% and Fe2O3 at 0.3%. Request the current analysis and reporting basis for the sample under consideration. These individual oxide figures do not establish every constituent or the performance of a finished formulation.
Set the optical and oil-test requirements separately
Obtain a current whiteness report using the reference required by the project. For oil absorption, request the actual procedure, units and sample result before using that measurement in a comparison. Keep moisture conditioning consistent with the agreed test programme.
Questions for the formulation trial
What binder or polymer will be used, and which processing and finished-material properties determine acceptance? Supply that brief with the sample enquiry. Evaluate the exact powder in the intended recipe and review any applicable certificate documents before making a final selection.
