  • FIRE-RESISTANT ARTICLE
    Publication number: 20240059886
    Abstract: A flame retardant article has excellent flame retardancy. The flame retardant article contains a cured resin member that is obtained by curing a thermosetting resin composition containing a thermosetting resin. The cured resin member forms an oxygen insulating carbonized layer when being burned. The cured resin member is present in at least a part of a surface of the expanded member obtained by expanding a thermoplastic resin composition containing a thermoplastic resin. The thermoplastic resin generates a residue when heated to 600° C. at a temperature increase rate of 10° C./minute under a nitrogen atmosphere.
