摘要：PURPOSE: A composition for forming polyurethane is provided to prevent bubble generation upon porting by a sealing material of hollow fiber module, thereby capable of improving operation efficiency of a hollow fiber module. CONSTITUTION: A composition for forming polyurethane consists of base material containing isocyanate component, and a hardener containing polyol component. The composition comprises one or more kinds of foaming inhibitor selected from a group consisting of calcium oxide, magnesium oxide, barium oxide, calcium hydroxide, magnesium hydroxide, barium hydroxide, magnesium silicate, aluminum silicate, magnesium aluminate and diatomite, and an urethane diluent, which is dimethyl propionic acid or 4-(hydroxymethyl)cyclohexane carboxylic acid.
