Environmentally Friendly Flame Retardant Synergist SF-400S
Our newly upgraded grade SF-400S delivers superior flame retardancy and smoke suppression versus the original SF-400 base model.
Core Advantages
- Lower loading level while retaining full flame retardant rating
- Outstanding smoke suppression and dense char layer formation
- Complete 1:1 replacement for antimony trioxide (ATO) across most PVC formulas
- Greatly optimized cost performance & wider formulation adaptability
SF-400S is an eco-friendly tin silicate flame retardant synergist. It works perfectly with halogenated flame retardants and brings remarkable smoke inhibiting effects. All batches pass third-party testing to meet EU RoHS and REACH environmental standards.
This product can fully substitute ATO, cutting overall raw material costs for flame retardant polymer compounds.
It boasts ultra-high thermal stability, alongside minimal water solubility and moisture absorption. No discoloration or thermal decomposition occurs under high-temperature extrusion/injection molding. There is no hydrolytic precipitation during processing, and the material’s electrical insulation properties remain intact.
