CYLINDRICAL ARTICLE AND METHOD FOR MANUFACTURING THE SAME

WIPO Patent Application WO/2001/036831

A1

A cylindrical article (1), characterized in that it comprises a porous cylindrical body (2) comprising PTFE resin and a coating film layer (5) which comprises a resin of different type from PTFE and is formed on at least one of the inner circumferential face (7) and the outer circumferential face (8) of the body in a state wherein the coating layer enters partially into through holes (6). The coating film layer can be formed through application of the resin in a solution form on s surface of the body. The cylindrical article has excellent mechanical strength and is free from the exfoliation of the coating film layer. Further, the formation of the coating film layer from a fluorine-containing resin, a crosslinkable resin such as an imide resin or a PES resin leads to providing a cylindrical article (1) having excellent mechanical strength and thermal resistance. For the use thereof as a fixing belt, it is preferred to form the coating film layer (5) only in an area of an inner circumferential part (3) and to thereby take advantage of the releasing property of the PTFE resin and the impregnation capability of a silicon oil.
