Fire Retardants: Ammonium polyphosphate is widely utilized as a fire retardant in various materials. When exposed to heat, it releases phosphoric acid, which forms a protective char layer on the surface of the material. This char layer acts as a barrier, slowing down the combustion process and reducing the spread of flames. ...

Zhang et al. [15]took APP and red phosphorus (RP) as flame retardants, added them into CPCM composed of PA/EG/ER, and made use of the synergistic flame retardant effect of the two flame retardants to prepare a new type of flame retardant CPCM. When the ratio of APP to RP is 23/10, the maximum limiting oxygen index (LOI) is …
