Abstract
The present invention relates to a composition for forming an environmentally friendly polyurethane foam, the composition having improved storage stability, air permeability, and anti-oxidation characteristics and to a method for manufacturing a polyurethane foam and, more specifically, to an isocyanate pre-polymer prepared by reaction of a polyisocyanate and a polyol component comprising a bio-polyol, to a composition for forming an environmentally friendly polyurethane foam, the composition having improved storage stability, air permeability, and anti-oxidative characteristics by comprising the pre-polymer as one component, to a method for manufacturing a polyurethane foam using the same, and to an environmentally friendly polyurethane foam manufactured thereby.
