To provide excellent foam forming methods in a foamable system comprising at least one hydrohaloolefin.SOLUTION: The foam forming methods comprise: (a) producing a foamable system comprising at least one hydrohaloolefin; and (b) ensuring either (i) substantial absence of long-term decomposition-inducing contact between hydrofluoroolefin and an amine-containing catalyst, (ii) an effective amount of surfactant being available in the system under conditions which prevent long term exposure of the surfactant to a long-term decomposition reaction atmosphere; or (iii) a combination of (i) and (ii).SELECTED DRAWING: None 【課題】少なくとも１種類のヒドロハロオレフィンを含む発泡性の系での良好なフォーム形成方法を提供する。【解決手段】（ａ）少なくとも１種類のヒドロハロオレフィンを含む発泡性の系を製造し；そして（ｂ）（ｉ）ヒドロフルオロオレフィンとアミン含有触媒との間に長期間分解誘発接触が実質的に存在しないこと；又は（ｉｉ）有効量の界面活性剤が、界面活性剤の長期間分解反応雰囲気への長期間の曝露を阻止する条件下において系中で利用可能であること；又は（ｉｉｉ）（ｉ）及び（ｉｉ）の組み合わせ；のいずれかを確保する；ことを含むフォーム形成方法。【選択図】なし
