  • Patent number: 6004641
    Abstract: A plastisol article is having an outer surface which has the look and feel of suede is provided. The article is made from a plastisol composition which includes expandable microspheres. A mold is dipped into the plastisol composition, withdrawn from the composition, and heated. The coated mold is heated at a temperature sufficient to expand the microspheres throughout the extent of the plastisol layer and to rupture the microspheres at the surface of the plastisol layer. The time and temperature at which the plastisol layer is heated causes only the microspheres substantially at the outer surface of plastisol layer to rupture. Substantially all of the microspheres within the plastisol remain unruptured. The expandable plastisol may be applied directly to a product or it may be applied over a layer of solid (unexpandable) plastisol. The expandable plastisol composition may include a blowing agent.
