Abstract
Granules containing mixtures of silica powder and cross-linked rubber powder are used in the manufacture of battery separators or vehicle tires. A granule contains silica and rubber powders in proportional amounts that form a silica powder carrier within which rubber powder particles are distributed. Incorporating silica-rubber granules in the manufacturing process of polyethylene separators offers a way to limit water loss in and improve the cycle life of a deep cycle lead-acid battery. Incorporating silica-rubber granules in the manufacturing process of vehicle tires affords advantages including easier material handling, reduced production of dust, and reduction in the number of ingredients measured and added to the formulation.
