Flame retardants are the chemicals used in thermoplastics, thermosets, textiles and coatings to arrest the spread of fire. There are basically two ways to improve flame retardancy, namely additive and reactive. It was observed that the reactive modification enhances flame retardancy of polymer to the greater extent than the additive route. Hence in this review, more emphasis is given to the reactive approach. Following review depicts various flame retardants that can be incorporated to thermoplastic and thermosetting polymers, their mechanism of action and their combined effect on flame retardant properties of polymer system in which they are incorporated in.

“…Because of the large bond energy of SiOSi bond and high flexibility of molecular chain, silicone owns better thermal stability and attracts the favor of researchers. The flame‐retardant mechanism of organosilicon FR is generally considered to be a condensed phase FR, that is, a cracked carbon layer is formed, and the thermal stability of carbon layer is improved . When the polymer burns, the silicon atom migrates to the polymer surface because of its lower surface energy, forming a SiO 2 layer covering the substrate surface as a protective layer and barrier to block the heat transmission.…”

A novel phosphorus‐containing silicone flame retardant (PDPSI) was prepared by Mannish reaction, and a series of PDPSI/PET composites were prepared by melt blending method. The nuclear magnetic resonance (1H NMR), Fourier transformation infrared (FTIR), and the thermogravimetric analyzer (TGA) results indicated that PDPSI showed network structure and owned good thermal stability, with the char residue of 62.2% at 800°C. The flame retardancy of PDPSI/PET composites was characterized by limiting oxygen index (LOI), vertical burning tests (UL‐94), and cone calorimeter (CCT). The results revealed that the addition amount of PDPSI was 5%, the LOI value of PDPSI/PET composites increased to 27.3%, and UL‐94 test passed V‐0 rating. When the PDPSI loading was 3%, PET composites showed excellent flame retardancy and smoke suppression, with a decrease in the peak heat release rate (PHRR) by 71.19% and the total smoke release (TSP) reduced from 14.4 to 11.1m2. The scanning electron microscopy (SEM) and FTIR results of char residue demonstrated that the flame‐retardant mechanism of PDPSI was solid phase flame retardant. PDPSI catalyzed the aromatization reaction of PET to promote the formation of a dense and continuous carbon layer, finally improving the flame retardancy and smoke suppression properties of PET.
