Invista’s Integrated Nylon 6,6 Polymer Facility, Shanghai, China


Shanghai HMD plant

Invista broke ground for the construction of a new hexamethylene diamine (HMD) plant and a nylon 6,6 polymer plant at the Shanghai Chemical Industry Park in China, in March 2014.



The world's biggest chemical company BASF announced plans to build its first process catalysts manufacturing plant in Asia Pacific in December 2014.


The HMD plant became operational in April 2016, whereas the nylon 6,6 plant will be operational in the second half of 2016. The HMD facility is the world's most energy-efficient HMD plant.

The facility will serve the quickly growing Asia Pacific markets for a variety of nylon 6,6 applications. It will also provide customers with a local resource for the production.

Details of the new hexamethylene diamine and nylon 6,6 polymer plants

The hexamethylene diamine plant has a production capacity of 215,000t a year, whereas the nylon 6,6 polymer plant will have a production capacity of 150,000t a year. Invista further plans to add a 300,000t adiponitrile (ADN) plant at the site in the future using its proprietary technology. The three plants will be located adjacent to each other.

The land reservation agreement for the nylon 6,6 plant was signed with the Shanghai Chemical Industry Park Development Company in 2013.

The new plants are expected to be among the world's most energy-efficient nylon intermediates sites and will be equipped with Invista's most advanced technologies for ADN, HMD and polymer production. The combined investment on the three plants will exceed $1bn, marking the biggest investment ever undertaken by Invista.

Applications of nylon 6,6 products

Hexamethylene diamine, adiponitrile and nylon 6,6 polymer products are used in the production of nylon 6,6 fibres and polymers that are eventually used to manufacture automobile parts, airbags, apparel, carpet, outdoor equipment and more.

Nylon 6,6 products are used in certain fibre applications such as industrial textiles and apparel, as well as engineering polymer applications in automotive electrical, consumer and industrial markets. They also provide significant advantages in various applications over other materials that are traditionally used in the country.

Project purpose and history

Invista decided to invest in new nylon polymer facilities in order to meet the growing demand for the products in Asia. China was chosen as the preferred location to construct the world-scale HMD, nylon 6,6 and ADN facilities after evaluating a number of sites.

Invista received environmental impact assessment (EIA) approval for the HMD plant from the Shanghai Protection Bureau in January 2013 and also received Wholly Foreign-Owned Enterprise status from the Chinese authorities.

"The HMD plant became operational in April 2015, whereas the nylon 6,6 plant will be operational in H2 2016."

The company signed a Land Reservation Agreement with the Shanghai Chemical Industry Park Development for the nylon 6,6 polymer plant, which would be sited in the Shanghai Chemical Industry Park (SCIP), in May 2013. The agreement was for additional land near to the planned HMD and ADN plants.

Contractors involved

WorleyParsons was awarded the engineering, procurement and construction management (EPCM) contract for the HMD plant in October 2013.
