Calcium carbonate is one of the earliest and largest fillers used in the rubber industry. Being filled in a large number of rubber products can not only increase the volume of the products, but also save expensive natural rubber or synthetic rubber to achieve the purpose of reducing costs.
Improved processing performance:
In the process of rubber processing, in order to shape the needs, attaches great importance to its processing performance. In the general formula of rubber products, it is often necessary to add several parts of calcium carbonate. Among the light-colored fillers, calcium carbonate has the best dispersibility, can be mixed with rubber in any proportion, and other additives can be mixed together, which is convenient for mixing. In addition to the above advantages, the calcium carbonate produced by Huidong has a prominent advantage that the change of its addition ratio will not affect the vulcanization system of rubber.
