Overview

Cooperative flame retardancy improves limiting oxygen index in rigid polyurethane foam, indicating a viable eco-friendly approach.

Key Points

  • The research aims to enhance the flame retardancy and performance of rigid polyurethane foam using a cooperative gas-condensed phase system.
  • Hybrid modification of rigid polyurethane foam using DOPO and MMT.
  • One-step all-aqueous foaming process was employed.
  • Variation of DOPO content to achieve optimal performance.
  • Sample with 8 wt% DOPO achieved a limiting oxygen index of 22.8% and UL-94 V-0 rating.
  • Peak heat release rate reduced by 66.40% and total smoke production reduced by 75.13%.
  • Best compressive property with peak energy absorption efficiency of 48.20.
