ADM Flame Retardant for PU LeatherThose of you working on flame retardancy for PU leather know the drill—Adding flame retardants is easy; the real challenge is ensuring performance isn’t compromised afterward. Too much flame retardant makes the leather stiff and reduces its softness, leading to cu
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.
For Class B1 rigid foam insulation boards, adding 10–14 parts of red phosphorus flame retardant can reduce the FIGRA value to below 100 W/s while maintaining a closed-cell rate of over 87%. Compared to aluminum hydroxide-based systems, this results in annual savings of approximately $20,000 to $30,000 in flame retardant costs. Silver-coated red phosphorus is available in both powder and paste forms, making it suitable for both manual and continuous production lines.
As yellow phosphorus prices navigate a period of post-decline volatility, our latest market analysis explores how shifting raw material costs are triggering a critical industry 'shakedown' for downstream phosphorus-based flame retardants.
Inorganic flame retardants such as ATH and MDH require high loading levels in TPU to achieve the required flame retardancy rating; however, high loading levels severely degrade the material’s mechanical properties and flexibility. Through nano-blending strategies—such as the physical barrier effect of nano-clay layers and the carbonization mechanism of expandable graphite—it is possible to enhance flame retardancy while reducing the amount of inorganic additives, thereby providing an alternative to phosphorus-based flame retardants for TPU.
