<p><P>PROBLEM TO BE SOLVED: To provide a fluororesin molding having an excellent chemical resistance and gas permeability, and also having a small linear expansion coefficient by melt molding. <P>SOLUTION: The fluororesin molding method comprises a step of molding the fluororesin comprising fluororesin particles of a multilayer construction which has, as an inner layer, at least a layer consisting of the fluororesin having a multilayer construction comprising at least two kinds of fluororesins different in melting point, and having a higher melting point than that of the outermost layer fluororesin, at temperatures lower than the melting point of the fluororesin of the highest melting point, not lower than the melting point of the outermost layer fluororesin, and not lower than the lowest melting point among the melting points of the fluororesin constituting the outermost layer when the fluororesin particles of the multilayer construction comprises plural kinds. Further, a fluororesin molding produced by the method is provided. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
