  • Methods of manufacturing embossed resinous products
    Patent number: 4022643
    Abstract: A method of manufacturing an embossed resinous product having a textured surface which comprises: forming a potentially foamable resinous composition containing a blowing agent therein; heating the potentially foamable resinous composition to an elevated temperature to activate the blowing agent to cause blowing of the potentially foamable resinous composition; and then, before the freshly blown resinous composition has cooled to ambient or room temperature and while it is still relatively soft, mechanically embossing the freshly blown resinous composition under pressure by applying to its surface a previously blown, chemically embossed resinous product having a suitably textured surface; and cooling the freshly blown and now embossed resinous composition to yield an embossed resinous product.
