| Abstract: | The paper gives empiric formula of the density of rigid polyurethane foams, relatingwith amount of blowing agents and atmospheric pressure. The results calculated by the formula are appoximate to that measured. The influences of atmospheric pressure and density etc. on the dimensional stability of rigid PU foams are also discussed. |
