For a long time, China's nylon 66 self-sufficiency rate has been low, mainly because the core raw material adiponitrile technology has not achieved a breakthrough
.
However, under the trend of automobile lightweight and environmental protection and energy saving, the demand for nylon 66 continues to rise, and with the breakthrough of domestic adiponitrile production technology, the east wind that promotes the development of nylon 66 industry has gradually blown
As we all know, the nylon 66 industry faces high barriers to development, presenting an oligopoly pattern in the world
.
At present, the main suppliers of nylon 66 are INVISTA, DuPont, Solutia, Rhodia, BASF, Randy Asahi Kasei, etc.
Nylon 66 cannot be used on a larger scale due to long-term constraints on the shortage of key raw material adiponitrile
.
The production process of adiponitrile is relatively long, the catalyst system is complicated, and the reactants also contain highly toxic cyanide, and the technical barriers are higher
From a domestic perspective, it was not until 2015 that Tianchen Company broke through the butadiene-based adiponitrile technology route and achieved a breakthrough
.
According to statistics from Zhuo Chuang Information, as of the end of 2020, there are about 7 nylon 66 manufacturers in China, with a total production capacity of 560,000 tons, an output of 387,000 tons, and a capacity utilization rate of 69.
It is understood that the country is currently stepping up the construction of nylon 66 industrial chain projects
.
For example, Chongqing Huafeng Polyamide Co.
From the perspective of demand, according to IHS data, in 2018, about 40% of the global nylon 66 consumption was used in the field of synthetic fibers, and 60% was used in the field of engineering plastics
.
The demand for nylon 66 in the field of synthetic fibers tends to be stable.
In the field of engineering plastics, nylon 66 is used in the automotive, electrical and electronic, and industrial machinery fields, accounting for a relatively high proportion of 45%, 16%, and 11% respectively
.
After modification, nylon 66 is mainly used in the production of auto parts
Huaan Securities analyst Liu Wanpeng believes that the total national demand for nylon 66 will be about 1.
32 million tons in 2025, with an average annual compound growth rate of 25% from 2021 to 2025; the total national demand for nylon 66 will be about 2.
88 million tons in 2030.
The compound annual growth rate from 2026 to 2030 is 17%
.
On the whole, the current domestic production of nylon 66 is insufficient to meet market demand, and nylon 66 still needs to be imported
.
However, the proportion of net imports in domestic nylon 66 consumption has been declining year by year, the supply structure has been gradually optimized, and the import substitution effect has increased day by day
