Abstract
Provided is an expansive refractory material that not only has excellent fire resistance but also can provide a heat insulating function for protecting a content by expanding to form a heat insulating layer when the refractory material is brought close to a heat source or comes into contact with flame. The refractory material at least includes: discontinuous reinforcing fibers having a thermal conductivity of 4 W/(m·K) or higher; and a flame-retardant thermoplastic resin, wherein the discontinuous reinforcing fibers are dispersed in the refractory material. The refractory material has a post-expansion porosity of 30% or higher.
