How can fire-resistant doors and Windows meet one-hour fire resistance at present

At the present stage of the refractory doors and Windows market, the fire Windows that can meet the fire resistance for 1 hour are basically steel frame or steel and wood composite frame plus composite fire glass in principle.

The application of expandable graphite in flame-retardant plastics is mainly based on its expansibility and adiabatic property. For example, the expansion of graphite sheets dispersed in polyurethane foam can prevent combustion, reduce the fire, but also play a role in heat insulation.

- Brief description of fireproof expansion seals for clad doors and Windows
