Fire safety is a crucial aspect of the industry, and Fire-Retardant Polymer Composites (FRPCs) have emerged as effective materials for improving safety in industrial settings. They are developed by introducing fire retardant additives to reinforced polymers, which improve their resistance to fire hazards. This review article explores the applications of FRPCs in various industrial settings. FRPCs are widely used in the construction industry, where they are incorporated into building materials like insulation, cables, and wall panels. They are also used in the transportation industry, where they are utilized in the manufacture of vehicles like planes, trains, and cars. FRPCs find application in the energy sector, where they are used in wind turbines, oil rigs, and electrical insulation. The effectiveness of FRPCs in improving fire safety is attributed to their excellent thermal stability, low combustibility, and high char formation. These properties enable them to withstand the high temperatures and combustion pressures associated with fire hazards. FRPCs have good mechanical properties, are lightweight and easily processed, making them ideal for use in industrial settings. The various fire-retardant additives used in FRPCs and the manufacturing techniques employed to create these materials were examined. This study highlighted the advantages and limitations of FRPCs and discussed the current and potential future applications of these materials. The need for continued research and development of FRPCs to improve their properties and increase their applications in industrial settings was highlighted. FRPCs are effective materials for improving fire safety in industries. Their inherent properties and ease of processing make them ideal for use in various industrial sectors and sustained research is required to improve their properties and increase their range of application in industries.
