Formulation and Qualification Notes
For transparent PVC and coating systems, check haze, dispersion and appearance at the selected loading. Flame-retardant performance must be assessed in the complete formulation.
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.
