Thousand-ton long carbon chain nylon elastomer project put into production

On November 25, the second phase of Weihai Xinyuan New Materials Co., Ltd.’s aldehyde-free environmentally friendly water-based adhesive project and the kiloton long carbon chain nylon elastomer project were held in the Chemical Industrial Park of Weihai Wendeng Economic Development Zone. A completion and commissioning ceremony was held. These two projects are the second phase of the entire new material project. The first phase of the high-end new material production project has been successfully put into production at the end of 2022.

Weihai Xinyuan New Materials Co., Ltd. is a wholly-owned subsidiary of Xinyuan Chemical (Shandong) Co., Ltd., located in the Chemical Industrial Park of Wendeng Economic Development Zone. Since its establishment, it has been engaged in the research and development and production of high-end new materials. It is the only company in China with a complete industry A leading fluorosilicone rubber manufacturer in the chain, it is a national high-tech enterprise. The company has worked closely with Yang Wantai, an academician of the Chinese Academy of Sciences, and established the country’s first pilot base led by the academician.

Long carbon chain polyamide elastomer has the advantages of light weight, good chemical stability, high elasticity, wear resistance, good low-temperature flexibility, fatigue resistance, and excellent tissue compatibility. It is a typical representative of advanced polymer materials and is used in many fields. Has a wide range of applications.

According to the different monomers, long carbon chain polyamides are divided into AB type and AABB type. The industrialized varieties of AB type include polyamide 11 and polyamide 12, and the industrialized varieties of AABB type include polyamide 1010, polyamide 1012, polyamide 1212, etc.

Thousand-ton long carbon chain nylon elastomer project

On May 28, 2022, the China Petroleum and Chemical Industry Federation organized experts to hold an online meeting on the “Development of Long Carbon Chain Polyamide Elastomers” completed by Xinyuan Chemical (Shandong) Co., Ltd. and the Institute of Chemistry, Chinese Academy of Sciences. , Industrial Production and Processing Application Key Technologies” Scientific and Technological Achievements Appraisal Meeting.

The appraisal expert committee formed an appraisal opinion that: this scientific and technological achievement created a polyamide elastomer with AABB type long carbon chain polyamide as the hard segment, developed an industrialized preparation technology for long carbon chain polyamide elastomer, and achieved a typical application demonstration. Overall, it has reached the international advanced level.

Xinyuan Chemical (Shandong) Co., Ltd. has built a 100-ton industrial production line and will achieve stable supply in 2021. The products produced are suitable for molding processes such as supercritical foaming, and lightweight and highly elastic materials have been successfully prepared for use in the manufacturing and sales of high-end sports shoes.

The appraisal committee recommended further expanding the industrial production scale of long carbon chain polyamide elastomers, increasing promotion efforts in high-end shoe materials, professional sports equipment and medical industries, and breaking the long-term dependence on imports of high-end elastomer materials.

Since then, a team led by researcher Dong Xia of the Institute of Chemistry, Chinese Academy of Sciences, has cooperated with Shandong Guangyin New Materials Co., Ltd., Xinyuan Chemical (Shandong) Co., Ltd. and other companies to build a kiloton-level production line for long carbon chain polyamide elastomers, which is the The project was reported to be put into production.
