Formulation and Qualification Notes
Select D202 through trials in the complete PVC stabilizer package. Validate processing stability, color and transparency under the intended exposure and service 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.
