Antimony Trioxide (ATO) has been the dominant flame retardant in PVC formulations. Yet since September 2022, export restrictions imposed by the Chinese government have triggered unprecedented volatility. Also, ATO prices have surged day by day... This crisis leaves global PVC compound manufacturers in urgent need of alternatives, as ATO remains their sole compliant solution under traditional formulations.
Mflam BS-25 is halogen free Phosphorus-Nitrogen flame retardant, which could be used in PVC industry, partially or completely 100% replace Antimony Trioxide (ATO).
