Disclosed are a polyurethane composition, a molded article, and a vehicle comprising the polyurethane composition or the molded article. The polyurethane composition comprises a polyol composition (A) in which polyether polyol (a1) and polymer polyol (a2) are mixed at a predetermined amount, an isocyanate composition (B) obtainable by polymerizing polyether polyol (b2) and an isocyanate composition (b1) that comprises i) methylene diphenyl isocyanate (M-MDI) and ii) polymethylene diphenyl isocyanate (P-MDI). As such, the molded article such as a vehicle seat pad can be manufactured with improved static and dynamic comfort.

Composition for manufacturing polyurethane foam and molded article thereof

A polyurethane filter foam is provided herein. The polyurethane filter foam may have improved permeability by having both a small cell and a large cell in a range for maximizing the opening property of the foam. In some instance, this is achieved by specifically configuring and foaming a composition of polyether polyol and methylene diphenyl diisocyanate (MDI) to manufacture the polyurethane foam. The polyurethane foam of the present invention can be manufactured without performing a reticulation process.
