Dang Guodong, the deputy general manager of the company, has been awarded the honor of "Shandong Province Innovation Role Model".
According to the work deployment of the regular "Discovering Role Models" activity, since March this year, the Organization Department of the Provincial Party Committee has organized and carried out the special activity of "Discovering Role Models · Innovating and Concentrating Efforts at the Front Line", focusing on the key tasks of the province's "Ten Innovations", and discovering, promoting and publicizing the advanced models and exemplary figures who have performed outstandingly at the front line of innovation. Party organizations at all levels in the province have earnestly organized and widely mobilized. Starting from grassroots Party branches, a large number of Party members have actively participated in recommending and discovering candidates for role models. After recommendations at all levels, review and approval, comprehensive comparison and selection, solicitation of opinions, and public announcement, 104 provincial-level "Innovation Role Models" have been determined. Dang Guodong, the deputy general manager of the company, is on the list.

Breaking the foreign import monopoly of polysulfone series resin materials and achieving domestic substitution has always been the goal pursued by Haoran. And research and development is the key to achieving this goal, as well as the driving force and support for Haoran's continuous development. Industrializing the research and development achievements in a practical way is also the theme of my lifelong work. This university professor, who has come to the front line of the enterprise's research, development and production on a full-time basis from a well-known domestic university, is quietly making contributions to the enterprise and society in his own position. He is Dang Guodong, the deputy general manager of Shandong Haoran Tersu Co., Ltd.


From technicians to engineers, everyone held their breath, determined to come up with excellent production technology. Just as the saying goes, "Their spirit is aroused at the first roll of the drums, wanes at the second, and is exhausted at the third," and many entrepreneurial stories come to an abrupt end at the stage of "exhaustion at the third roll of the drums". However, in the face of the previous failures, Dang Guodong had his own opinion: "Although we failed in the previous attempts, we made progress each time and got closer to success with every try. Success doesn't come overnight. Our team has the ability to conduct research and development and the perseverance, which are the essence of our vitality. We will surely succeed and break through the difficulties."

Finally, in the fourth year of research and development, the performance indicators of the polysulfone material reached the standards of similar foreign products, and it was officially put into industrial production. The company became the first and currently the only enterprise in China to produce and sell polysulfone resin, a special engineering plastic, at a kiloton level. With its superior quality and excellent cost-performance ratio, Haoran Tersu quickly rose to the forefront of the domestic market. The company's products achieved the highest market share in the domestic market, and many manufacturers came to cooperate out of admiration. Thus, the door to the leapfrog development of Haoran Tersu was opened. Words like "the highest market share" have become the driving force for Dang Guodong to lead the team in continuous research and development. Only by making continuous progress and maintaining technical and cost advantages can the company better meet the needs of the market.

As the demand for polysulfone resins in the domestic market continues to grow and the application fields of polysulfone products in multiple industries keep expanding, orders are pouring in one after another, which has become a "sweet burden" for Haoran. Besides the guarantee of excellent product quality, the credit also goes to the attentive service provided by Dang Guodong's R&D team. As the person in charge of technology research and development and product production, Dang Guodong has become an "after-sales service specialist" who goes to customers' doors to offer services. Originally, after customers received the polyphenylsulfone products, if they encountered problems during the processing of products such as baby bottles and tableware, the sales staff would describe the problems or send photos remotely to seek the help of the R&D team to solve them. Leaving aside the time and distance between the two parties, the fact that the sales staff and technicians have their own areas of expertise alone made problems that were not originally difficult become troublesome. In order to not only do a good job in product research and development but also ensure that the service does not hold back, Dang Guodong personally provides after-sales services to customers. He truly makes customers feel at ease with the excellent product quality and reassures them with the simple and direct service method.

At present, the medical materials market is booming and has entered a "golden period". There is huge room for import substitution of the main raw materials for many medical devices, and medical-grade polysulfone is one of them. Relying on the strong support of the industrialization experience of polyphenylsulfone products, Dang Guodong's team has set their sights on the research and development of high-end polysulfone in the medical field. They have once again embarked on the journey of "domesticating" medical-grade polysulfone resin. They have cooperated with Sichuan University to carry out a research project on the key technologies for the industrialization of medical-grade polysulfone raw materials, focusing on the large-scale production of special resins for polysulfone membranes used in hemodialysis. After the completion of the project, it will achieve import substitution, help domestic high-end medical products such as hemodialyzers to be completely localized, and lay an important technical foundation for the industrialization of domestic medical-grade polysulfone. In the field of new materials, although domestic brands like "Horan" are gradually taking root in the high-end market, customers still habitually place more trust in international big brands. Dang Guodong will lead the R&D team to continuously break through and innovate, striving to develop more independent products to replace imports. The road to realizing the localization of raw materials is long, but he has always been on this journey.
