Precipitated Calcium Carbonate

Increased Rear Resistance The addition of Calcium Carbonate also increases the tear resistance of the rubber. These three advantages apply to both natural and synthetic rubber.Thus it is not a surprise to see Calcium Carbonate used as an additive for small rubber products (soles of shoes) as oil seals and auto parts, as well as large products as tyres, tape, and rubber hoses. Because of its ability to neutralize stomach acid, calcium carbonate is found in some over-the-counter antacid products, such as Tums and Rolaids
