China Ground Calcium Carbonate for Rubber - Quality Suppliers and Factory Direct Pricing
Product Description
Useen ground calcium carbonate enhances shoe sole wear resistance and comfort, while improving appearance and extending lifespan.
Useen ground calcium carbonate is a highly effective filler that increases the hardness and wear resistance of shoe soles, thereby extending their lifespan and reducing the need for frequent replacements. Furthermore, Useen ground calcium carbonate has excellent dispersibility, improving the uniformity and appearance quality of the soles while lowering raw material costs. It also effectively reduces the density of the soles, making the shoes lighter and more comfortable for prolonged wear.
Ground calcium carbonate can improve the wear and aging resistance of rubber tubing, extending its lifespan and enhancing stability.
Ground calcium carbonate can improve the wear resistance of rubber tubing, especially in environments with high friction, extending the service life of the tubing. It can also enhance the aging resistance of rubber tubing, reducing the impact of factors such as ultraviolet radiation and oxidation, and improving its stability during long-term use.

Frequently Asked Questions
Q
What is ground calcium carbonate (GCC) and how is it used in rubber products?
A
Ground calcium carbonate (GCC) is a natural mineral filler derived from limestone. In rubber products such as shoe soles and tubing, it is used to improve hardness, wear resistance, and dimensional stability, while also helping to reduce overall production costs.
Q
How does Useen ground calcium carbonate extend the lifespan of shoe soles?
A
Useen GCC increases the hardness and wear resistance of shoe soles, reducing surface abrasion during daily use. Its excellent dispersibility also ensures uniform distribution within the sole material, enhancing structural integrity and prolonging the product's service life.
Q
Can ground calcium carbonate improve the aging resistance of rubber tubing?
A
Yes. Ground calcium carbonate effectively enhances the aging resistance of rubber tubing by reducing the degrading effects of ultraviolet radiation and oxidation. This ensures the tubing maintains its mechanical properties and stability throughout long-term use in demanding environments.
Q
What are the key quality specifications of Useen ground calcium carbonate for rubber applications?
A
Useen GCC features a CaCO₃ purity of ≥97%, average particle size of ≤45μm, brightness of ≥95%, moisture content of ≤0.4%, and a pH value between 8–10. These specifications ensure consistent performance and compatibility with rubber formulations.
Q
Does Useen offer OEM or customized product services?
A
Yes. Useen provides flexible OEM services, allowing customers to customize product specifications, particle sizes, and packaging formats to match their specific application requirements, helping to optimize costs and avoid unnecessary features.
Q
Is Useen ground calcium carbonate environmentally friendly?
A
Absolutely. Useen operates its own green mine raw material production base, forming a sustainable industrial chain that integrates environmentally friendly material sourcing with advanced nano material deep processing, ensuring minimal environmental impact throughout the production process.
