High-Quality Precipitated Calcium Carbonate (Rubber) from China Suppliers and Factory - 25kg/500kg Packaging
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.
