Formulation and Qualification Notes
The MgO mass-fraction value is not magnesium hydroxide purity. Choose the loading and surface-treatment requirements for the base polymer, then validate processing, mechanical properties and the required finished-product fire test.
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.
