Abstract: The present application provides an intumescent flame-retardant coiled material for cables and an intumescent flame-retardant cable. Specifically, the intumescent flame-retardant coiled material for cables comprises a thermal expansion layer and a combustible armor layer adjacent to the thermal expansion layer. The intumescent flame-retardant cable comprises a cable core; a thermal expansion layer adjacent to the cable core; and a combustible armor layer adjacent to the thermal expansion layer. The intumescent flame-retardant coiled material can be used for mounted and curved cables and can provide excellent flame-retardant performance while providing effective mechanical protection for cables.

Abstract: Disclosed is a temperature-indicating composite material product and a manufacturing method and application thereof, the temperature-indicating composite material product comprising: a porous film (1), opaque to at least a portion of visible light or opaque to at least a portion of visible light and at least a portion of ultraviolet light; and a colored composite material layer (2) located at the lower surface of the porous film (1), wherein the colored composite material layer (2) comprises a macro-molecular connecting material, a crystalline material and a colorant. Preferably, the macro-molecular connecting material is a crosslinked pressure-sensitive adhesive material, wherein the crystalline material and the colorant are dispersed in the macro-molecular connecting material, and the macro-molecular connecting material is an amorphous material or has a melting point higher than that of the crystalline material. When heated and melted, the crystalline material may migrate into the porous film (1) and fill pores therein, making the porous film (1) transparent to visible light.
