Preparation and Performance Study of Pyrophosphoric Acid Piperazine and Tannic Acid Synergistically Intumescent Flame‐Retardant Polypropylene
To address the inherent drawbacks of polypropylene (PP), including high flammability, severe melt dripping during combustion, and significant mechanical property deterioration after flame retardant incorporation, a novel halogen‐free intumescent flame retardant (IFR) system was developed in this work by blending natu...
