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.

Low-density polyurethane foam composition as sound-absorbing material having improved appearance formability, smell reduction and sound absorption performance, method for manufacturing polyurethane foam and polyurethane foam manufactured therefrom

Disclosed are a fiber for a sound-absorbing material for vehicles and a sound-absorbing material for vehicles including the same. The cross-section of the fiber for a sound-absorbing material includes a first end portion, a second end portion spaced apart from the first end portion, and an intermediate portion connected to the first end portion and the second end portion. The intermediate portion includes at least three bent portions. Each of the first end portion and the second end portion has a width larger than the width of the intermediate portion.
