Explore Pipe Joining →China’s antimony export restrictions, mine curtailments, and U.S. trade policy have sent ATO spot pricing to multi-year highs with 2.5–3 month lead times industry-wide.
Flamisol supplies three zinc-based synergists specifically qualified for ATO reduction and replacement in halogenated PVC, polyolefin, and engineering plastic compounds.
China's export controls on antimony — classified as a strategic material in 2024 — combined with mine curtailments and U.S. trade policy have pushed ATO spot pricing to multi-year highs with 2.5–3 month lead times across major distributors. IARC Group 2B classification for Sb₂O₃ is simultaneously triggering specification reviews in automotive, wire and cable, and electronics applications, compressing the timeline for compounders who have been deferring alternative qualification.
The practical question for procurement is not whether to evaluate alternatives — it is which zinc-based synergist is the right fit for a given substrate and fire standard. FL-ZS, FL-ZHS, and FL-ZB each have distinct mechanisms, smoke suppression profiles, and substrate compatibilities. The comparison table on the Zinc Synergists page covers all three side by side with ATO.
Inorganic FR synergist and smoke suppressant for PVC, polyolefins, engineering plastics, thermosets, and rubber. Partial ATO replacement in brominated systems.
FL-ZHS Zinc Hydroxystannate—ZnSn(OH)₆Hydrated zinc stannate with superior smoke suppression. Primary product for flexible PVC wire and cable where NBS or IEC smoke density limits apply.
FL-ZB Zinc Borate—2ZnO·3B₂O₃·3.5H₂OMultifunctional: FR synergy, smoke suppression, afterglow suppression, and char promotion. Works in halogenated and halogen-free systems.
