Ningbo Changhong Polymer Scientific and Technical Inc. is a high-tech enterprise in the thermoplastic elastomer (TPE) industry. Since its establishment, it has been focusing on the R&D, production and sales of styrene-based thermoplastic elastomers (TPES). The company insists on independent research and development, continuously improves the research and development capabilities of the full range of TPES products, and has achieved fruitful results in hydrogenated TPES, namely SEBS and SEPS technologies. At the same time, the company focuses on market development and changes, and on the basis of continuing to enrich and improve the existing SBS and SEBS product series, deepens the practice of supply-side structural reforms, accelerates the construction of SEPS production capacity, and promotes the development of China's SEPS industrialization, strives to realize the R&D, production and sales capabilities of the full range of TPES products, and provide high-performance, high-value-added environmentally friendly new materials for the implementation of the healthy China strategy to build a beautiful China, to replace traditional low-end, low-environmental protection performance materials, and continue to meet people鈥檚 increasing needs for a better life.
As a key product of the "13th Five-Year Plan" for the new materials industry, TPES is a new type of polymer developed and a major breakthrough in the theory and application of polymer materials science and engineering. It has both the dual performance and broad characteristics of rubber and thermoplastics, showing high elasticity of rubber at room temperature and can be plasticized and molded at high temperature. It is a new type of polymer material that can replace traditional synthetic rubber and is an upgrade of traditional synthetic rubber. The variety is known as the "third generation rubber" after natural rubber and synthetic rubber.
The company鈥檚 TPES production technology has reached the advanced level of the industry. Relying on stable and good product quality, the company鈥檚 brand awareness has been continuously improved. It has established long-term and stable cooperative relationship with major upstream and downstream customers and suppliers. At the same time, the company is also actively pushing product internationalization process.
