China Factory Suppliers of Precipitated Calcium Carbonate (PCC) for Rubber and Industrial Applications
product description
Improving the strength and wear resistance of gloves, extend their service life.
The use of Useen precipitated calcium carbonate effectively enhances the strength and abrasion resistance of gloves, making them more durable and long-lasting in daily use, reducing the frequency of replacement due to wear and tear. Secondly, precipitated calcium carbonate improves the processability of rubber, helping to reduce production costs. Furthermore, the addition of precipitated calcium carbonate also enhances the tensile strength and tear resistance of the rubber, improving the protective performance of the gloves and increasing their resistance to external physical impacts.
Reducing raw material costs, improve the flowability of the rubber compound.
Adding Useen precipitated calcium carbonate during tire production can significantly reduce raw material costs and improve the flowability of the rubber compound, making the mixing and molding processes more stable and easier to operate. It also helps to improve the dimensional stability of the rubber and enhance its rigidity and shape retention. Furthermore, Useen calcium carbonate can improve the heat resistance and aging resistance of the rubber compound, making it a commonly used and cost-effective filler material in tire manufacturing.

Frequently Asked Questions
How does precipitated calcium carbonate improve rubber product performance?
Precipitated calcium carbonate (PCC) acts as a functional reinforcing filler that enhances mechanical properties such as tensile strength, tear resistance, and wear durability. It also improves compound flowability, dispersibility, and dimensional stability during processing.
What is the role of fatty acid activator in this product?
The fatty acid surface treatment changes the calcium carbonate particles from hydrophilic to hydrophobic, dramatically improving their compatibility, dispersion, and bonding within organic rubber matrices and polymer systems.
Can Useen customize the particle size and oil absorption values?
Yes. Through our professional R&D center and OEM capabilities, we can adjust technical parameters including oil absorption, whiteness, particle size distribution, and surface activation to meet specific customer requirements.
Why is PCC preferred over ground calcium carbonate (GCC) in gloves and tires?
PCC features finer, more controlled crystal structures, higher whiteness, and customizable surface modifications compared to GCC, delivering superior reinforcement, anti-aging benefits, and smoother surface finishes in precision rubber items.
What are the recommended storage conditions for this material?
It should be stored in a dry, cool, and well-ventilated warehouse away from moisture, rain, and direct sunlight. Ensure bags remain tightly sealed to maintain a maximum moisture content below 0.5%.
