摘要: Disclosed are a polyurethane foam composition for sound-absorbing materials, a method for manufacturing a polyurethane foam and a polyurethane foam manufactured using the method. Particularly, disclosed are a composition containing a polyol mixture including a polyol and an additive, and isocyanate, and the manufacture of a low-density polyurethane foam for sound-absorbing materials, which is imparted with improved appearance formability, reduced smell and enhanced sound absorption performance by controlling the content of the composition and the conditions for foaming the composition.
