If the mesh is finer than 0, the thermal expansivity tends to decrease, and if the mesh is finer than 150, the thermal expandability is extremely reduced, and as a result, the flame retardant effect of the foam is reduced. On the other hand, if the particle size is large, for example 20 to 3
If the mesh is around 0, the thermal expansion property is sufficiently high, but it becomes difficult to uniformly disperse into the ribbon dead foam, and the desired flame retardance cannot be obtained. At the same time, the dispersibility into the foam raw material is not good, resulting in poor work efficiency. decreases. Therefore, the particle size of the thermally expandable graphite used in the present invention is preferably 30 to 100 mesh, and most preferably 40 to 80 mesh.
