To achieve efficient flame retardancy in TPU materials, the alignment of the decomposition temperature of phosphorus-based flame retardants with the substrate is crucial, as it directly impacts flame retardancy efficiency and property retention. The differences in the application of various types of phosphorus-based flame retardants in TPU is a subject worth in-depth exploration.
How can TPU flame retardancy be improved without compromising its excellent physical properties? The combination of inorganic flame retardants and nano-compositing technology discussed in the article is one key approach, and expandable graphite, as a highly efficient synergistic flame retardant, is offering new possibilities for solving this challenge.
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.
