Background

Polyamide (PA), commonly known as nylon, is a widely used polymer with a wide variety, among which PA6 and PA66 have the largest output. At the end of 2019, PA6 capacity in China exceeded 5Mt/a, while the number for PA66 was about 0.5Mt/a. In the future, the development potential of nylon industry in China will be huge.

Currently, PA66 production in China is seriously restricted by its key raw material of adiponitrile (ADN) technology. Therefore, China has issued several policies to encourage and promote the development progress of domestic ADN technologies. In Feb 2019, INVISTA launched the design of a 0.4Mt/a ADN production base in Shanghai, which is scheduled to start production in 2022. Besides, several domestic enterprises and scientific research institutions, i.e. Pingmei Shenma, Tianchen Qixiang, Yangquan Coal, etc., are exploring the R&D and Industrialization of ADN technologies, and have made significant progress.

The layout of China’s PA6 value chain is increasingly perfect, and the development of the key feedstock of caprolactam (CPL) is relatively mature. The promotion of ammoxime process with independent intellectual property rights helps rapid development of CPL. At the end of 2019, CPL capacity in China was about 4Mt/a. In the future, China’s CPL industry will continue a fast growing and new projects will be invested intensively, leading to a predicted total capacity of about 10Mt/a by 2025. Meanwhile, with the increasing attention paid to green environmental protection & sustainable development, bio-nylon has become a hot topic. The development & industrialization of raw material production, polymerization technology and product application of PA5X and PA1212 are accelerated.

ADN, CPL & Polyamide Value Chain Forum 2020 will be organized by ASIACHEM in Q2. The upcoming conference will discuss current status & future trend of PA & key feedstock industry, development & industrialization of ADN new technologies, bio-nylon (i.e. PA56) technologies, CPL technology & projects investment, high-value applications and prospect of nylon downstream. Besides, the industrial visiting will be arranged.
