When the physical barrier provided by expandable graphite meets the chemical flame retardancy of red phosphorus, rubber flame retardancy finally breaks free from its “reliance on halogens” and moves toward “high-efficiency synergy.”
When exporting polyurethane flame retardants, the regulatory frameworks—including the EU’s REACH, Southeast Asia’s TISI, and new energy aging tests—each follow different logic. Which scenarios are best suited for red phosphorus, paste-form products, and phosphorus-nitrogen synergistic systems, respectively? This article outlines the selection criteria for these three markets to serve as a reference for export-oriented manufacturers.
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.
