With the rapid development of China's chemical industry and petrochemical sector, significant progress has been made in the scientific research and technological development within the field of mass transfer and separation engineering. The most notable achievement has been the development and application of various new types of packing materials. The continuous introduction of new packing materials and technologies in the construction of new separation towers and the retrofitting of old ones has greatly improved separation efficiency, processing capacity, product quality, and energy savings in tower separation equipment, resulting in substantial economic and social benefits.

Our company began developing tower packing materials in the 1970s. In collaboration with Tianjin University, Shanghai Jiao Tong University, Zhejiang University, Shanghai Chemical Industry Research Institute, and the Fourth Design Institute of the Ministry of Chemical Industry, we have developed new types of packing materials with the strong support of experts from domestic universities, colleges, and design institutes specializing in packed towers. We now offer nearly a hundred varieties across two major series: random packing and structured packing. These products have been widely adopted by large and medium-sized enterprises in China, including Dushanzi Refinery, Zhenhai Refining & Chemical Co., Ltd., Shanghai Baosteel Group, Shanghai Coking Company, Handan Iron and Steel Plant, Ningbo Beilun Power Plant, Zoucheng Fertilizer Plant, and Shandong Haihua Coal Industry, receiving high recognition from our customers.
