TF-241 P and N based flame retardant containing carbon sources for polyolefin, HDPE
TF-241 P and N based flame retardant containing carbon sources for polyolefin, HDPE
Introducing our TF-241 P and N based flame retardant for polyolefin, HDPE. Our factory produces high-quality carbon-containing flame retardants for plastic materials.
The core advantages of using the blend APP TF-241 has a flame retardant in polypropylene (PP) are as follows.Firstly, TF-241 effectively suppresses the flammability of PP, enhancing its fire resistance. This is crucial in applications where fire safety is a priority.Secondly, TF-241 has excellent thermal stability, preserving the structural integrity of PP under high temperatures. It also helps reduce smoke release and toxic gas emissions during combustion, mitigating potential health hazards.Additionally, TF-241's compatibility with PP is superb, ensuring easy integration and consistent performance.Overall, the synergistic mixture of TF-241 demonstrates its core advantages as a flame retardant for PP.
