Ground Calcium Carbonate (GCC) for Plastics - Quality China Suppliers & Factory Products
product description
Useen ground calcium carbonate to plastics like PVC, PE, and PP enhances impact resistance, improves processing performance.
Adding Useen ground calcium carbonate to plastics such as PVC, PE, and PP can improve their impact resistance, making pipes less prone to breakage or damage when subjected to external forces. The addition of ground calcium carbonate also helps improve the processing performance of plastic pipes, making the production process smoother. It improves material flow, reduces friction during processing, lowers energy consumption, and simultaneously increases production efficiency and optimizes the manufacturing process.
Useen ground calcium carbonate improves adhesive tape stability, ensures uniform adhesive distribution.
Useen ground calcium carbonate can improve the adhesion and stability of adhesive tapes. It can regulate the distribution of the adhesive in the tape, making it more uniform during use, and increasing the bonding force between the tape and the adhered surface, thus enhancing the adhesive effect of the tape
