Switching to Ca-Zn stabilizers: formulation and process checks
Moving to a calcium-zinc system involves more than replacing the previous stabilizer at the same loading.

Moving to a calcium-zinc system involves more than replacing the previous stabilizer at the same loading. Assess compatibility with the lubrication balance, filler, pigment and processing window. Selecting a lead-free system does not automatically establish compliance of the finished product.
Priorities during a conversion trial
Track initial colour, longer-term heat stability and surface quality separately. Record deposits, flow and line-cleaning needs. Use the supplier's recommended dosage as a starting point and set acceptance limits against your own specification. Include feedstock variability in the trial plan when recycled material is used.

ASSAFE — Calcium-zinc (Ca-Zn) PVC stabilizer
Select a Ca-Zn system together with PVC resin, filler, plasticizer, lubrication balance and processing temperature. Initial colour and long-term thermal stability are distinct targets. Validate the grade and dosage through a production trial; the Ca-Zn designation is not automatic certification of the finished product.

Review destination-market and application-category restrictions before selecting a lead-based system. Technical performance does not establish regulatory suitability. When evaluating a Ca-Zn alternative, compare thermal stability, lubrication balance and finished-product tests together.
