Abstract
Latex capable of being creamed is thickened by creaming the latex at least partially, introducing a hydrophilic thickening agent into at least a portion of the serum produced, and mixing the treated serum with the cream. The latex may be normal, concentrated, or diluted, and vulcanized or unvulcanized. The latex may be creamed by centrifuging, by the introduction of a creaming agent such as ammonium alginate, pectin, locust bean gum or Irish moss, or by both methods. Thickening agents mentioned are colloidal clays, sodium silicate, casein, glue, gelatine, gum tragacanth, Irish moss, karaya gum, alginates, and pectin bodies. An example showing suitable proportions is given.
