APPLICATION:




ADVANTAGES:


Calcium Carbonate used can cut costs, and it can improve the heat resistance, size stability, and hardness of the base material. Calcium carbonate is the filler first used by the rubber industry, and is still used in the greatest quantity. Adding large amounts of calcium carbonate to rubber can increase the product's volume, which conserves the use of expensive natural rubber and thereby cuts costs. 


The addition of calcium carbonate to rubber increases tensile strength, abrasion resistance, and tear resistance even more than does vulcanization. Calcium carbonate also has a significant reinforcing effect in both natural and synthetic rubber, and can improve consistency. Calcium carbonate is used in such small rubber products as oil seals and auto parts, and also in such large products as tires, tape, and rubber hoses. Not only is calcium carbonate used alone as a reinforcing filler, when needed, it may also be used together with such other fillers as carbon black, white carbon black, clay, and titanium white to achieve reinforcing, filling, coloring, improving workability, enhancing product performance, and reducing latex content. Calcium carbonate may also partially replace such more-costly white fillers as white carbon black and titanium white.


Ground calcium carbonate is used in a wide variety of rubber applications as both an extender and detacktifying agent. In other calcium carbonate rubber applications, it can add stiffness or provide abrasion resistance.
