PURPOSE:To obtain a fluorine-contained resin foam having uniform and fine closed cells and high degree of expansion, by adding polyether compound to a fluorine-contained resin, and molding the fluorine-contained resin in a molten state under heating. CONSTITUTION:100pts.wt. fluorine-contained resin having >=50wt% fluorine content, 20,000-10,000,000 number-average molecular weight, and 0.5-30g/10min melt index is blended with 0.01-5pts.wt., preferably 0.05-10pts.wt. polyether compound shown by the formula (R<1> is H, etc.; m is 2-30,000) having 300-1,000,000, preferably 1,000-50,000 average molecular weight and two or more ether groups, and molded in a molten state under heating. |
