Development History

The company was founded in 1997, and its early technology mainly came from the close cooperation of Hangzhou Research Institute of chemical industry, one of its shareholders. Hangzhou Research Institute of chemical industry is the first scientific research institute engaged in the research and development and production of paper chemicals in China, mainly producing rosin sizing agent. In 2004, the company absorbed and merged Huake Fine Chemical Co.,Ltd. to expand the product range to PAM dry strength agent, papermaking wet strength agent, softener, stripping agent and other series of papermaking chemicals. At the same time, we also introduced a new polyacrylamide enhancer technology from Hangzhou Hanghua Harima Chemicals Co., Ltd. Subsequently, the company's technology gradually moved from introduction and absorption to independent development, and established the "Hangzhou Hanghua Harima paper chemicals high tech R & D center". At present, the company has completed the declaration of 7 national invention patents, of which 5 have been authorized by the national invention patent, and the other 2 are in the public stage.
