ABSTRACT:
A liquid mixture containing a liquid polymeric material and a granular filler is injected into a mold (11) for centrifugal molding and subjected to centrifugal molding, thereby preparing a cylindrical body including a homogeneous dispersion layer (2) having the filler homogeneously dispersed in the polymeric material and a high-density packed bed (1), formed on the outer peripheral surface side or on the inner peripheral surface side of the homogeneous dispersion layer (2), containing the aforementioned polymeric material more densely filled with the aforementioned filler. The high-density packed bed (1) is removed for exposing the surface of the homogeneous dispersion layer (2). According to this structure, the yield of the elastic cylindrical body can be improved.
