The most recent information regarding antimony production is as follows:

1. In 2022, the global output of antimony ore totaled around 111,000 metric tons, with China accounting for more than half of this production at a contribution rate of 54.5%.

2. By July 2023, antimony ingot production in China continued to increase. According to reports on August 28th, 2023, the production of antimony ingots reached 7,670 tons in July, an increase of 1,140 tons (a month-on-month growth of about 17.5%) and a year-on-year rise of 1,810 tons (a year-on-year growth of approximately 30.9%). Cumulative antimony ingot production until July was 43,620 tons, growing by 2,310 tons compared to the same period last year, representing a year-on-year increase of about 5.6%.

3. Concurrently, the output of antimony trioxide also increased during the same period in July, reaching 9,830 tons, with a monthly increase of 390 tons.

4. Regarding imports, from January to May 2023, China saw nearly double the amount of imports of other antimony ores and concentrates compared to the previous year, showing significant growth.

In summary, throughout 2023, China maintained its leading position in the global antimony market despite potential resource constraints and stronger environmental regulations. For the latest developments, please refer to the most up-to-date official statistical data or industry reports.

Hongtaiji has been professional in flame retardant for 20 years, and its products meet international environmental protection requirements: (1) EU ROHS directive (2) REACH regulatory standards. Obtained ISO9001:2015, ISO14001:2015, ISO45001:2018 management system certification. Independent research and development of melamine cyanurate (MCA), microencapsulated red phosphorus, melamine pyrophosphate (MPP), polyolefin halogen-free flame retardant, acid fire retardant coating, acrylic flame retardant, and other environmentally friendly flame retardants.

The halogen synergist (FR-0520) developed and patented by our company is a product composed of environmentally friendly organic and inorganic substances that have undergone chemical modification. It exhibits outstanding synergistic effects with halogen-based flame retardants, and its heavy metal content has been tested and certified by SGS to meet international environmental management substance directives. In most plastics such as PA, PBT, ABS, HiPS, PS, PVC, PP, PE, and EVA, FR-0520 can be used as an equivalent replacement for antimony trioxide (Sb2O3), providing comparable synergistic flame retardant properties and superior smoke suppression capabilities. When used to replace antimony trioxide at equal amounts, not only does it maintain the flame retardant rating of the end products, but it also significantly reduces the amount of smoke generated during combustion. Furthermore, this product possesses anti-drip characteristics, effectively improving the high-temperature melt dripping phenomenon often observed during burning.

Utilizing our halogen synergist (FR-0520), there are advantages both in terms of environmental friendliness and cost compared to antimony trioxide (Sb2O3), making it an excellent alternative to the latter.

The usage ratio of brominated compound: FR-0520 should be applied at a ratio of 3:1 or 2:1.
