Poly(piperazine phosphonate) Flame Retardant
Poly(piperazine phosphonate) is a polymeric nitrogen-phosphorus flame retardant that combines the char-promoting condensed-phase action of phosphorus with the gas-diluting effect of nitrogen in a single macromolecular structure. Its polymeric nature results in low volatility, non-migration, and excellent thermal stability, making it suitable for high-temperature polymer processing. It provides effective flame retardancy in polyamides, polyesters, and halogen-free cable compounds.
