After falling nearly 20% from its monthly average, the price of yellow phosphorus rebounded to 27,000 yuan per metric ton; costs for phosphorus-based flame retardants, which had just seen some relief, are now facing upward pressure again. Environmental inspections in Guizhou may lead to tighter supply, and the window for downstream procurement is narrowing.
Bromine prices rose by 1,500 yuan per metric ton for the week, and cost pressures on bromine-based flame retardants continue to mount. With tight supply and manufacturers holding back on sales, prices are more likely to rise than fall in the short term; downstream companies should focus on managing their procurement schedules and evaluating halogen-free alternatives.
Polyurethane for automotive interiors must simultaneously meet three standards: FMVSS 302 flame retardancy, low misting (≤2 mg), and low odor (VDA 270 ≤3.0). The phosphorus-nitrogen synergistic system limits the flame retardant loading to 16 parts, achieves an LOI of 29–30%, and meets the V-0 rating, while also reducing the contribution of volatile compounds, providing a viable path for formulation balance.
In June, bromine prices plunged over 13%, weakening cost support for brominated flame retardants. With raw material prices declining and demand in the traditional off-season, the flame retardant market saw weak volume and price performance, while the halogen-free substitution process may accelerate.
Bromine prices surged by RMB 6,500/ton in a single week, continuously intensifying cost pressures on downstream flame retardants. Multiple factors—including geopolitical tensions in the Middle East, low operating rates, and tightened imports—have driven the strong upward trend, with the industry focusing intensely on supply-side developments.
Flame Retardants Deep Inside the Cell: The synergistic effect of high heat-resistant ceramic-coated separators and phosphorus-containing flame-retardant electrolytes enables immediate pore closure and ion channel blockage at 160°C during nail penetration tests, achieving no smoke emission from single cells and zero thermal runaway propagation in modules. This provides dual insurance for lithium battery flame retardancy at both the cell and battery pack levels.
