PVC Lead Salt Stabilizer Phase-Out
Problembeschreibung
Export pipe fittings were rejected by customers due to lead salt stabilizer, non-compliant with environmental regulations
Ursachenanalyse
Lead salt stabilizers are effective but highly toxic, restricted by regulations such as EU RoHS; calcium-zinc stabilizers are the mainstream replacement, and organotin is used for high-transparency food grade; formulations must be oriented according to target market regulations
Lösung
①Use calcium-zinc or organotin stabilization systems for export products; ②obtain supplier compliance declarations; ③regularly update the target market regulation list; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Wichtigste Erkenntnis
Stabilizer selection has become a compliance issue; lead salt phase-out is the trend, select the system oriented by market; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
