ABSTRACT:
A method of felting porous polychloroprene latex foam to obtain desired properties. Such felting renders the finished foam suitable for controlled ink flow required for printing purposes. The felting is accomplished by reducing the volume of the porous polychloroprene latex foam and heating at a temperature of 400.degree. to 460.degree. F. for five to ten minutes.
