摘要
A coextruded block composite which includes a porous first block. The block is permeable to fluids and includes a granular component and a binder component. The block has interconnected pores therethrough having a first average diameter. The composite also includes a second block. In addition, at least one of the first block and the second block is continuous and at least a portion of the second block is contiguous with at least a portion of the first block. The second block also may be permeable to fluids. Additional blocks may be present, if desired. One or more of the blocks other than the first block may be a porous block having a granular component and a thermoplastic binder component. The coextruded block composite may be employed as a filter medium.
