FUSION-BONDED PRODUCT FROM NON-POROUS MATERIAL AND POROUS MATERIAL

摘要

A fusion-bonded product prepared by fusion-bonding a part of a laminate containing a non-porous material and a porous material, characterized in that the cross section of the fusion-bonded portion comprises at least three layers comprising a layer (A) consisting of the non-porous article alone, a composite material layer (B) containing the non-porous material and the porous material being present mixedly, and a layer (c) consisting of the porous material alone, wherein the boundary between the composite material layer (B) and the porous material layer (c) has a length (LBC) in the range of 1.2 mm to 2.5 mm. The fusion-bonded product exhibits excellent resistance to release.
