Nanjing Chuangbo takes the lead in developing the integrated process technology of drying-free PET reaction foaming in the world, relying on a solid theoretical foundation, complete testing methods and advanced processing equipment technology, through cooperation with upstream Sinopec and downstream product enterprises and machinery manufacturing enterprises. In 2018, it successfully developed the first 4,000-ton/year industrialized PET foaming production line in  China. Currently, there are more than ten industrial production lines in stable operation across China.
