China Ground Calcium Carbonate (GCC) Suppliers & Factory for Improved Rubber Processability
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.
