Monthly Report: Antimony Prices Eased Slightly in September—With Both Antimony And Bromine Prices at Record Highs, How Much Longer Can Flame Retardants Hold Out?

Antimony trioxide saw a moderate decline in September, but bromine prices continued to rise; with both bromine and antimony prices high, cost pressures on flame retardants remain unabated. The antimony market is expected to fluctuate weakly in October, with the pace of downstream restocking and the resumption of mining operations in Myanmar serving as key variables.

Flame-retardant PP Is Replacing HIPS And ABS

Flame-retardant PP is rapidly replacing traditional flame-retardant HIPS and ABS in the home appliance and electronics sectors thanks to its lightweight properties (20% weight reduction) and cost advantages (37% cost reduction). Compared to HIPS/ABS, which suffer from relatively high prices and mediocre resistance to yellowing and aging, flame-retardant PP has emerged as the preferred alternative due to its low cost, lightweight properties, and excellent resistance to aging. Yinsu Flame Retardants offers bromine-antimony and phosphorus-nitrogen-based flame retardant solutions to meet various environmental and cost requirements.

[Monthly Review of Yellow Phosphorus And Phosphorus-Containing Intermediates]: Prices Showed An Overall Upward Trend (August 2026)

In August, the average monthly price of yellow phosphorus rose 4% month-over-month and 22% year-over-year, keeping costs for phosphorus-based flame retardants under sustained pressure. However, due to weak downstream demand, industry-wide oversupply, and difficulties in passing on cost increases, price hikes for flame retardants were limited, squeezing profit margins. In September, stockpiling ahead of the two major holidays may drive yellow phosphorus prices higher still, and cost support remains strong. Until end-user demand shows a noticeable recovery, the phosphorus-based flame retardant market is expected to maintain a pattern of “high costs, weak demand, and tight profit margins,” with profit recovery still contingent on a revival in consumption.

Antimony Prices Bottom Out and Stage a V-Shaped Rebound; Market Returns to the 100,000 Mark (July 31–August 7)

Antimony prices have completed a V-shaped bottoming-out and rebound, with No. 1 antimony ingots rising from 90,000 yuan per metric ton to 100,000 yuan per metric ton, while antimony trioxide has risen in tandem. Refineries are becoming increasingly reluctant to sell, leading to a sharp decline in low-priced supply. Yinsu Flame Retardants offers antimony-free and low-antimony solutions, such as the composite antimony substitute FR-03 and the magnesium-aluminum layered flame retardant HAM-300V, to mitigate the impact of raw material price fluctuations on formulation costs.

Why Flexible PVC Loses Flame Resistance — The Plasticizer Problem

Weekly Report: Antimony Market Price Breaches 100,000 RMB for The First Time – Will This Key Level Hold? (July 3–July 10)

Antimony prices have fallen below the key level of 100,000 yuan/ton, temporarily easing cost pressures on antimony trioxide. The Ministry of Ecology and Environment has launched a public consultation on decabromodiphenyl ethane, making antimony substitutes and halogen-free flame retardant solutions a focus of industry attention.
