On September 24, 2021, the Hay Think team entered the production workshop of SDHR High Performance Engineering Plastics Technology Corporation. The intelligent CNC injection molding machine is working in an orderly manner, and injection molding products of different specifications and different materials are continuously being produced. And out, packaged and sent to all parts of the world.
SDHR is a high-tech enterprise dedicated to the research and development, production and sales of high-end polysulfone and polyetheretherketone[PSU/PESU/PPSU/PEEK] engineering plastics. It has built a "provincial polysulfone special engineering plastics engineering laboratory" and was rated as polysulfone special engineering plastics. "Invisible Champion Enterprise" in the field of engineering plastics. Since 2017, the company has achieved the first place in China for the production capacity and sales volume of a single product of polyphenylsulfone, with sales of over 100 million yuan, and has maintained the number one market share in China.
Focus on high-end product research and development, break years of foreign monopoly
Polysulfone series resins are the third generation of special engineering plastics developed after general plastics and engineering plastics. They are known as the "tip of the pyramid" in the plastics industry. Before the establishment of SDHR, polysulfone resin manufacturing technology was monopolized by German and American companies, and China's demand basically relied on imports, and there were no large-scale manufacturers.
The fourth-generation production line successfully developed by SDHR realized the stable mass production of polysulfone resin, and the material performance indicators reached the standards of similar foreign products. SDHR became the third polysulfone resin supplier in the world and the first and only special project in China. Thousand tons of plastic polyphenylsulfone resin production and sales enterprises. Due to the fact that the selling price is significantly lower than that of imported products and the stability of the products is strong, Haoran Te Plastics has gained a firm foothold in the domestic market and has also reduced the price of imported domestic products by more than 30%.
The company has 21 patents, annual R&D accounts for more than 5%, participated in the formulation of the "polyphenylsulfone (PPSU) resin" corporate standard, and successively undertook 1 national-level project, 3 provincial-level projects, and 12 municipal-level projects… "Only by continuing to focus on R&D, making continuous progress, and maintaining technological advantages and cost advantages, can we better keep up with market needs.
The company's newly built fifth-generation 3,000-ton polysulfone production line with an investment of 240 million yuan has completed trial production.
PESU/PEEK micropowder
Expand a variety of application areas
In 2017, after a market survey, the company found that the global membrane technology is developing rapidly, and the amount of polysulfone used in the polymer high-function membrane industry is increasing. Therefore, companies closely follow the market demand, adjust market strategies, strengthen independent innovation, and improve the core competitiveness of products. Based on the market situation, the R&D team independently develops and improves process technology according to the product performance characteristics of medical and water treatment applications, promotes the diversification of polysulfone product grades, and broadens the scope of product applications.
In September last year, the company established a long-term cooperative relationship with the scientific research team of Professor Dr. Zhao of Sichuan University to carry out a 1,000-ton medical-grade polyethersulfone raw material industrialization key technology research project, based on the successful experience of Haoran Special Plastics in the development of polyphenylsulfone resin. It mainly solves the key technical problems of molecular weight control of medical-grade polyethersulfone raw materials, purification of post-processing impurities and monomers, and difficulties in achievement transformation. It will help China's high-end medical products such as hemodialyzers to achieve complete localization, and solve the problem of localization of upstream raw materials. , Lays an important technical foundation for the industrialization of China's medical grade polyethersulfone, and is of great significance to promote the progress of the medical polymer materials industry.
