About Calcium Carbonate for Rubber

Calcium Carbonate for Rubber 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 our calcium carbonate use in rubber industry. application like:- Shoes & Slipper sole, Tyre tube straps, Floor Tiles, Mat, Conveyor, Belts Hoses tubes R.P. granules etc. Application : As a reinforcing filler and improve strength as well as whiteness. It imparts stiffness to non cured rubber product.

Superior Filler for Rubber Applications

Calcium Carbonate optimizes rubber products by increasing tensile strength and ensuring excellent dimensional stability. Its fine particle size and high whiteness contribute to a smooth, uniform surface finish, enhancing both the mechanical and aesthetic properties of rubber goods. Widely used in tyres, tubes, belts, sheets, and hoses, this versatile extender promotes longevity and reliability in rubber manufacturing.

Consistent Quality and Purity

With a purity level between 96% - 99% and an extremely low residue on 325 mesh (<0.1%), Calcium Carbonate guarantees consistent quality for demanding industrial use. Its controlled moisture and volatile matter, combined with a stable pH (8-9), enable predictable results across applications, reducing variability in production processes. Sourced, manufactured, and supplied in India, it meets industry standards for high-performance fillers.

Packaging and Storage Advantage

Packaged securely in 25 kg and 50 kg bags, this Calcium Carbonate is easy to handle, transport, and store. Its indefinite shelf life when kept dry ensures you can purchase in bulk without concern for degradation. The powder form allows effortless blending into rubber compounds, making it an efficient and economical solution for manufacturers and suppliers.

FAQ's of Calcium Carbonate for Rubber:

Q: How is Calcium Carbonate used in the rubber industry?

A: Calcium Carbonate is incorporated as a filler and extender during rubber compounding, enhancing product properties such as tensile strength, dimensional stability, and surface finish in items like tyres, tubes, sheets, belts, and hoses.

Q: What benefits does Calcium Carbonate offer for rubber manufacturing?

A: It improves tensile strength, provides excellent stability under compression, ensures a smooth and uniform surface finish, and contributes to low thermal conductivity and porosity, thereby increasing product lifespan and performance.

Q: When should Calcium Carbonate be added to rubber compounds?

A: Calcium Carbonate is usually introduced during the mixing phase of rubber production, allowing for uniform dispersion and optimal integration with other raw materials to achieve consistent mechanical properties.

Q: Where can I source Calcium Carbonate for rubber applications?

A: This high-quality Calcium Carbonate is available from exporters, manufacturers, suppliers, and traders throughout India, and can be ordered in bulk packaging suitable for industrial scale production.

Q: What is the typical process for handling and storing Calcium Carbonate powder?

A: Handle the powder in a dry environment and store it in sealed 25 kg or 50 kg bags to prevent moisture absorption. Proper storage guarantees indefinite shelf life and maintains the chemical characteristics essential for rubber manufacturing.

Q: How does Calcium Carbonate react with acids?

A: Calcium Carbonate effervesces when exposed to hydrochloric acid (HCl), releasing carbon dioxide gas-a characteristic useful for quality control testing and confirming product identity.

Q: What is the recommended usage rate of Calcium Carbonate in rubber products?

A: The exact rate depends on the desired product properties, but it is typically used in significant proportions as a filler to improve mechanical and surface characteristics without affecting the rubber's flexibility.
