Abstract
Porous rubber sheets suitable for bandages, garments or battery separators, are made by spraying a latex composition containing vulcanizing ingredients and non-volatile stabilizers, on to a heated deposition surface, or by spraying it alternately with a coagulant, under such conditions that a continuous layer of rubber is not formed. The backing surface may be thin metal foil, e.g. of aluminium or a knitted or woven fabric, which may be stretched round the periphery of a hollow drum through which a heated fluid may be passed, the latex being sprayed thereon by a series of spray guns during a number of revolutions. The sheet, with the backing, is then removed from the drum and vulcanized. For bandages it is then cut into strips and rolled, together with the backing; the composition may include a water soluble resin, e.g. the reaction product of a polyhydric alcohol with boric acid, to render the bandage self-adherent. Porous rubber stockings with or without a fabric backing may be formed by spraying on to an appropriately shaped former.
