Abstract
Disclosed are a low-carbon polyurethane foam composition and a method for preparing the same. The low-carbon polyurethane foam composition may have improved foam cell uniformity while contributing to carbon reduction goals as a result of applying a polyether carbonate polyol containing a carbonate bond. The method for preparing the low-carbon polyurethane foam composition may include reacting a polyol mixture including a carbonate bond-containing polyether carbonate polyol and a petroleum-based polyether polyol, an isocyanate, and a silicone surfactant.
