On November 26-27, the Additives Branch of the China Polyurethane Industry Association held the Polyurethane Additives Application Technology Conference and the First Annual Meeting of the Additives Special Committee in Haikou, which was a complete success.
Han Baole, deputy secretary-general of the China Polyurethane Industry Association, presided over the meeting and read a congratulatory letter from Zhao Zhiping, deputy secretary of the Party Committee of the China Petroleum and Chemical Industry Federation, and a speech by Yang Maoliang, chairman of the China Polyurethane Industry Association.
Zhao Zhiping said that polyurethane additives have a wide range of types and are widely used. They are an important link in the security of the polyurethane industry chain and supply chain, achieving “independent controllability” of additives, especially high-end additives, and “independent control” of the research and development and production of forging additives. “Killer” technology will remain one of the important directions for the entire industry to make up for its shortcomings in the future. He hopes that under the leadership of the China Polyurethane Industry Association Council and the Additives Branch, additive companies can open up a new chapter for the development of polyurethane additives and polyurethane materials through resource integration and division of labor. He also hopes that the Additives Branch will contribute to the development of polyurethane industry in my country. Innovation and development have made new due contributions, and the development of various additive companies is booming.
Yang Maoliang said that under the new development pattern, the establishment of the Polyurethane Additives Special Committee provides a good information exchange platform for the development of the additives industry, provides a basis for the linkage and cooperation of different additives, and lays the foundation for future polyurethane additives. The development of additives provides broad space. The field of polyurethane additives is an important battlefield for the security of the polyurethane industry chain and the transformation of innovative scientific and technological achievements. It has strong industrial soil and imagination space. The establishment of the Additives Branch is timely. It is hoped that through everyone’s joint efforts, the directors and deputy directors of the Additives Special Committee can unite relevant enterprises, gather strength and consensus, and coordinate with the special committees of the association to make contributions to the development of China’s polyurethane industry. Make positive contributions.
Lv Guoguo, secretary-general of the China Polyurethane Industry Association, said at the opening ceremony that polyurethane additives are important raw materials for the polyurethane industry. Although the dosage is small, the effect is huge. Because of its excellent performance, it is widely used in various fields of polyurethane. As the development of my country’s polyurethane industry shifts from a high-speed period to a high-quality period, it is increasingly important to focus on the application of polyurethane additives, expand new areas of polyurethane additive application, and promote the technological research and development and industrialization of polyurethane additives.
Zhou Jian, chairman of the Additives Branch of the China Polyurethane Industry Association and chairman of Suzhou Xiangyuan New Materials Co., Ltd., said that in April 2019, the China Polyurethane Industry Association established the Polyurethane Additives Branch. In order to promote the Additives Special Committee to better serve the industry and member companies, the Additives Branch adheres to the development concept of co-creation, sharing, and win-win, and has been reviewed and approved by the China Polyurethane Industry Association to organize this “First China Polyurethane” The first annual meeting of the Polyurethane Additives Professional Committee of the Industrial Association and the Polyurethane Additive Application Technology Conference will be held to build a platform for exchanges and services between polyurethane additives and polyurethane-related enterprises, institutions, experts and scientific researchers, and to work together with people in the polyurethane industry to Establish close ties to provide more systematic solutions for the polyurethane application field, apply more cheap and high-quality new varieties of polyurethane additives to the polyurethane field, and jointly promote the sustained and healthy development of China’s polyurethane additive industry.
Dr. Sheng Enshan, Executive Director of Huntsman Asia Pacific R&D Center, introduced the current status and development direction of polyurethane foaming agents. Sheng Enshan believes that although there are many foaming technologies, there is currently no “perfect” foaming agent, and the situation of ODS elimination is grim. In particular, the new HFC reduction regulations have added to the complexity of HCFC elimination work. The situation of HCFC and HFC replacement work in small and medium-sized enterprises is very not optimistic. He hopes that China’s polyurethane industry will continue to increase the application, product and technological innovation of foaming agents.
Wan Qihua, manager of the R&D Department of Jiangsu Aojia Material Technology Co., Ltd., introduced the application of polyurethane high-rebound special additives and mainly introduced the application of three types of additives. Among them, PF-228, as an imitation cold deformation additive, can prevent cold deformation of foam, increase foam stability, and can solve the cold deformation problem of T9 high rebound formula. An-33 is a gel-type low-odor catalyst that can improve early fluidity and effectively reduce sponge odor and amine catalyst contribution. UF-5361/UF-5378 is a low emission silicone stabilizer.
Chen Jinbiao, technical manager of Tianjin Li’anlong New Materials Co., Ltd., introduced anti-aging solutions for polyurethane. As the world’s leading supplier of anti-aging additive products and technologies for polymer materials, Li Anlong’s main products include antioxidants, light stabilizers and the overall solution product U-pack.

Chu Songtao, Marketing Director of Zhejiang Wansheng Co., Ltd., introduced the opportunities and challenges of flame retardants. He pointed out that the flame retardant industry is an industry driven by fire protection and flame retardant regulations. With the strengthening of fire safety awareness, fire protection and flame retardant regulations have received attention in various countries, which will promote the development of the flame retardant market. But found�The country’s building materials, furniture and home furnishings and other industries have relatively complete flame retardant regulations, but our country lacks regulations in this regard, and toxicity issues have become the key to restricting the development of the industry. He suggested that we should increase the research and development of new products (reducing toxicity and lowering registration fees); pay close attention to safety and environmental protection; develop new processes, reduce costs, increase efficiency, and expand scale; provide services and new product research and development for the needs of downstream customers, and provide the entire industry with Chain services; meet flame retardant requirements (basic) and industry performance requirements; develop green flame retardants to achieve green production processes and green recycling of end products.

Yan Jianrong, chief technical engineer of Shanghai Qike Fluorosilicone Materials Co., Ltd., introduced the factors and solutions to the yellowing of polyurethane soft foam sponges. Yellowing is one of the results of the aging of polyurethane soft foam and an important signal of changes in the structure and performance of polyurethane materials. By studying the yellowing mechanism of polyurethane materials, necessary theoretical support can be provided for the design, production and storage process improvement of yellowing-resistant polyurethane materials. Research on the raw materials and additives of polyurethane soft foam has pointed out the direction for its resistance to yellowing: choosing high-quality polyether polyols with low unsaturation without adding polymer polyols can effectively prevent double bonds from being oxidized, thereby preventing the foam from deteriorating. Yellowing; modified aliphatic diisocyanate can be grafted, copolymerized and other methods to improve the yellowing resistance while ensuring the use requirements of the product; develop green natural anti-yellowing additives and develop green, non-toxic anti-yellowing additives Agents have become a development trend.
