Review paper says PIN flame retardants can combine polymer fire safety, performance and sustainability. Based on over 100 references, this review presents advances in PIN FRs and their integration into innovative composite materials, in particular in electronics, transport and aerospace, and new research areas. PIN FRs are identified as effective in reducing flammability and also in reducing smoke generation, but with challenges of processing and materials performance. The range of PIN FRs available ensures widespread applicability and potential to contribute significantly to fire safety and sustainability in various industries. Developments include improving polymer compatibility, improving heat resistance and thermal stability (for processing, recycling). Focuses are provided on new polymer composites and on applications to ensure fire safety in electronics and transport.
