Invista and Solvay have signed a settlement agreement that resolves disputes related to adiponitrile (ADN) intellectual property and technology in use at their nylon 6,6/66 intermediates Butachimie joint venture in Chalampé, France. The settlement confirms Invista’s exclusive ownership of the ADN technology at Butachimie and includes a plan to upgrade the facility with Invista’s latest and most advanced ADN technology. The planned upgrade would be one of several components in a new joint venture relationship between the two companies.

Retrofitting Butachimie with Invista's newest ADN technology is expected to dramatically increase the plant’s efficiency. The Butachimie joint venture has been operating for 40 years, and is the world’s largest ADN facility. The nylon 6,6/66 intermediates made at Butachimie are used to make nylon 6,6/66  fibers and polymers that ultimately become part of air bags, automobile parts, carpet, workout apparel, outdoor equipment and more.

Invista is based in the United States. It has leading brands like Lycra, Coolmax, Cordura and Stainmaster. It is one of the world’s largest integrated producers of chemical intermediates, polymers and fibers. The company’s advanced technologies for nylon, spandex and polyester are used to produce clothing, carpet, car parts and other everyday products.

Solvay is a producer of essential chemicals including soda ash, caustic soda, hydrogen peroxide and special chemicals such as fluorinated products, ultra-fine fillers, high purity barium and strontium.
