Abstract
A rigid polyurethane foam composition characterized by containing 5 to 20% by weight of hollow-spherical Silas balloons having a particle size of 100 to 300 .mu.(based on the total weight of the polyol and isocyanate components of the polyurethane foam) and 0.2 to 2% by weight of an organosilane compound (based on the total weight of the polyol and isocyanate components of the polyurethane foam and said Silas balloons) in the rigid polyurethane foam.
