China Ground Calcium Carbonate (Rubber) Suppliers - High-Quality GCC from Reliable Factory
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
QWhat is ground calcium carbonate (GCC) and how is it used in rubber products?
Ground calcium carbonate (GCC) is a natural mineral filler derived from limestone or marble. In rubber products such as shoe soles and tubing, it is used to increase hardness, improve wear resistance, enhance surface appearance, and reduce overall production costs by partially replacing more expensive raw materials.
QHow does Useen ground calcium carbonate improve the lifespan of shoe soles?
Useen ground calcium carbonate increases the hardness and wear resistance of shoe soles, significantly extending their service life. Its excellent dispersibility also ensures a uniform distribution within the sole material, resulting in consistent quality and improved appearance, while making the soles lighter and more comfortable for extended wear.
QCan ground calcium carbonate enhance the aging resistance of rubber tubing?
Yes. Ground calcium carbonate effectively enhances the aging resistance of rubber tubing by reducing the degrading effects of ultraviolet radiation, oxidation, and other environmental factors. This results in improved long-term stability and a longer service life, even in demanding operating conditions.
QWhat are the key quality specifications of Useen ground calcium carbonate for rubber applications?
Useen ground calcium carbonate meets strict quality standards, including a CaCO₃ purity of ≥97%, brightness of ≥95%, average particle size of ≤45μm, moisture content of ≤0.4%, pH value between 8–10, and heavy metal content (as Pb) of ≤0.005 W/%. These specifications ensure consistent performance across rubber applications.
QDoes Useen offer OEM or customized product solutions?
Yes. Useen provides flexible OEM services, allowing customers to customize product specifications, particle sizes, packaging, and other parameters to suit their specific manufacturing requirements. This approach helps customers optimize costs by paying only for the features they actually need.
QIs Useen ground calcium carbonate an environmentally friendly material?
Yes. Useen operates its own green mine raw material production base, ensuring that all calcium carbonate products are sourced and processed in an environmentally responsible manner. The company has established an integrated industrial chain that combines eco-friendly raw material extraction with advanced nano material deep processing technologies.
