[Industry Focus]：After the localization of adipitrile (ADN), the nylon 66 market will be expanded, and China may become the world's largest PA66 market.

Adipitrile (ADN) is a colorless and transparent oily liquid, which has been hydrogenated to obtain hexadiamine (HMDA), hexanediamine is basically used to produce nylon 66, and hexanitrile has high technical barriers. China has not mastered this technology yet, and domestic consumption basically depends on imports.

At the same time, affected by force majeure such as cold wave and logistics, the supply of hexanitrile and hexanediamine has been affected all the time, and the price of hexanediamine has been running at a high level. Since it reached an all-time high of 82800 yuan/ton in 2018, the price of hexanediamine has always maintained a downward trend. It began to rise sharply at the end of 2020, reaching 63500 yuan/ton in April 2021. Its corresponding product nylon 66 began to decline all the way after reaching the price high point in 2018 and soared again in mid-202020. Since the beginning of 2021, it has risen from 30250 yuan/ton to 41750 yuan/ton, with the highest price reaching 43250 yuan/ton, which is the peak price since 2016.

Now the localization of hexanitrile has ignited the investment enthusiasm of downstream nylon 66, by the end of February, the downstream production capacity of more than 530 million tons of nylon 66 had been quietly on the road, and domestic nylon 66 began to enter the expansion period in 2022.

Nylon 66 has better comprehensive performance than nylon 6, but because the raw material adipitrile is not domestically produced, the cost is high, which limits and restrains the release of nylon 66 demand and the market growth. In the past five years, demand has been hovering around 40-500,000 tons/year, nylon 66 production capacity in 2020 is 560,000 tons/year, nylon 66 production capacity in 2021 is more than 70 tons, the apparent consumption of nylon 66 is about 600,000 tons, while the domestic nylon 6 Polymerization capacity reaches 5.34 million tons/year, the output and demand are about 4 million tons, and the consumption is less than 15% of nylon 6.

The localization of hexanitrile broke through the bottleneck of nylon 66 raw materials, and nylon 66 project began to compete for layout., the production enterprises of Shangma hexanitrile device basically matched the downstream nylon 66 device synchronously. Enterprises with raw material advantages directly started the nylon 66 device first. , by the end of February, 2022, the domestic planned construction scale also reached more than 530 million tons, and Hengshen, Yongrong and other Nylon 6 head production enterprises are making use of raw materials and market advantages, and are also laying out to Nylon 66 to form a double dragon drive of nylon 6-nylon 66 integration.

In the next two years, the new nylon 66 production capacity will increase. It is worth noting that there are chemical enterprises with raw materials entering the nylon 66 track, nylon 66 modified enterprises with insight into demand, traditional chemical fiber enterprises and other capital, adopt polymerization technology both continuous method and intermittent type, in the future, nylon 66 will enter the application scenario, integration and ecological track from a single product.

Replacing steel with plastic has become a trend. PA66 meets the demand of vehicle weight loss with various performance advantages such as light weight, heat resistance, high temperature resistance and high strength. New energy vehicles and rail transit have become the new driving forces for the growth of nylon 66 demand. Nylon 66 feels softer and more skin-friendly than nylon 6. The fiber has better breathability, abrasion resistance, temperature, sunshine and other adaptability than nylon 6. At present, nylon 6 fiber is mainly used for domestic civil clothing, nylon 66 fiber has not been used yet. With the localization of hexanitrile, nylon 66 fiber will be used for civil clothing including underwear, yoga pants, quick-dry pants, wind shield, shell jacket, etc. The application of PA66 in the field of textile and clothing will grow rapidly, bringing wider development space.

With the expanded application of nylon 66 in new energy vehicles, civil silk and other fields, its demand is also increasing year by year. In the next five years, China will become the world's largest nylon 66 market.
