Intrinsic Flame-Retardant rigid polyurethane foam via reactive Organophosphinate modification

Key Points

• The modification improved the flame-retardant properties of polyurethane foam, making it more effective in high-temperature conditions.
• Enhanced thermal stability was observed, showing a significant decrease in flammability after the organophosphinate treatment.
• Observational analysis of the foam's performance revealed a compliant structure that withstands thermal stresses better than untreated versions.
• Such advancements may enable broader use of flame-retardant materials in manufacturing applications, reducing fire risks.
