Formulation and Qualification Notes
The MgO mass-fraction value is not magnesium hydroxide purity. Compare this grade’s particle-size range with D102.5 during formulation screening; grade selection should be based on the actual compound and processing conditions.
The values shown are reference data for grade selection, not a finished-product performance guarantee. Confirm the current TDS, SDS and batch COA before qualification. Select the addition level through formulation trials and evaluate dispersion, processing and the required end-use properties.
