description | A process for molding foam products substantially free from flaws caused by air bubbles in the foamable reaction mixture wherein a foamable reaction mixture having a viscosity eta in cP between 100 cP and 2500 cP is introduced into a mold cavity through an opening in the mold wall and against the wall of the cavity opposite the opening of a mold in which the thickness of the cavity and the thickness s of the resulting molded product adjacent to the opening at the time the mixture is introduced into the cavity is maintained at 0.5 mm to 15 mm under conditions whereby the radial distribution rate wradial in m/sec., eta in cP and s combine to satisfy the relation wradial (m/sec) . s (mm) = |
