Raw Material ControlDeso Group cooperates with Borealis Chemical Industry, Hyosung Korea and other domestic and foreign raw material chemical giants. After entering the factory, raw materials are inspected through multiple processes to ensure the quality of raw materials and guarantee the quality of products from the source.
