Foam rubber may be prepared by shaping foamed latex into desired configuration and gelling it. The gelled latex may then be cut to the required thickness to provide articles e.g. cosmetic puffs. The shaping process may use a disposable mold circular polymeric casting or the mold may be permanent, e.g. glass, passing through a gelling chamber. The process reduces waste for products which has previously been cut from slab foam. |
