Product Description

Flame Retardant Used on Replacing Antimony Trioxide (Sb2O3), for PVC Compound Application
 

Product Description

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). This breakthrough innovation liberates manufacturers from ATO dependency while delivering superior performance and sustainability:

• Complete ATO Replacement: Fully replaces ATO about 1:1 in formulations without compromising flame retardancy (UL94 V0 achievable);
• Halogen-Free & Eco-Advanced: Phosphorus-Nitrogen synergistic system aligns with global environmental regulations (REACH, RoHS);
• Supply Chain Stability: China-based production ensures consistent quality and reliable supply; 
• Cost Predictability: Eliminate exposure to antimony price fluctuations and export license risks;
