  • Process for making a polyurethane foam sheet and composites including the sheet
    Patent number: 3989869
    Abstract: A process is provided for making a polyurethane mechanical foam adapted to be used as an interlayer between a plastic surface layer and a textile, the process involving frothing a non-ionic aqueous dispersion free from emulsifying agents of a polyurethane having a particle size of less than 1 micron, said dispersion containing more than 45% by weight polyurethane and a thickening agent whereby its viscosity of the dispersion is from about 10 to about 70 seconds with a Ford Cup having a 4 mm orifice to form a foamable mixture, spreading the frothed dispersion into a foamed film, and drying the resulting product.
