Antimony Flame-Retardant Masterbatch
The antimony flame-retardant masterbatch mainly uses antimony trioxide (Sb₂O₃) as its core ingredient. It is produced through melt compounding, which allows Sb₂O₃ to be evenly dispersed into a plastic carrier such as PE, PP, or PS.
When added to thermoplastics, this masterbatch acts as a synergistic flame-retardant additive, helping the material achieve higher flame resistance and improved fire-safety performance.
Antimony Functional Masterbatch
The antimony functional masterbatch is an upgraded version of the basic antimony flame-retardant system. It includes extra functional additives—such as anti-dripping agents (like PTFE) and antioxidants—to meet more demanding application needs.
With these additives, the masterbatch provides stronger fire resistance, better thermal stability, and enhanced mechanical performance, making it suitable for applications that require multifunctional protection.

Increased Processing Efficiency
Enables single-pass processing with negligible material loss, leading to reduced raw material consumption and overall cost savings.
Superior Dispersion and Flame Retardancy
Exhibits excellent dispersion within the polymer matrix, resulting in enhanced flame retardant performance. Maintains mechanical properties and thermal stability, even after multiple processing cycles.
Equivalent Dosage Compatibility
Designed for additive dosage equivalence with conventional powder-based flame retardant systems, facilitating seamless substitution in existing formulations.
