Oil-in-water emulsions, and their use

This invention discloses a composite material consisting of layers of a plastic sheet, a polyurethane ionomer latex foam and a textile material.

Composite materials and processes for their production

Plastic sheet adhered to polyurethane ionomer latex foam

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.
