Formulation and Qualification Notes
For PVC applications, balance the grade with the full stabilizer package and validate heat stability in the actual resin 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.
