FD440 is a specialized flame retardant additive designed as a 50% replacement for Antimony Trioxide (ATO) in PVC cable applications. It provides an effective balance of flame retardancy, cost efficiency, and environmental sustainability, making it a versatile solution for modern cable formulations. 
Key Features and Benefits:
Enhanced Flame Retardancy: FD440 enhances the flame resistance of PVC cables by promoting char formation and reducing flame propagation. It works synergistically with halogenated systems to achieve excellent fire performance.
Reduced Toxicity: By replacing 50% of ATO, FD440 minimizes toxic fume emissions during combustion, ensuring compliance with stringent safety and environmental regulations.
Cost Optimization: FD440 reduces dependency on ATO, lowering raw material costs without compromising performance.
Compatibility: The additive blends seamlessly with PVC formulations, maintaining critical mechanical, electrical, and thermal properties of the cable.
