Koch Industries-owned chemicals and energy firm Flint Hills Resources is expected to transfer its propylene business to chemicals and materials manufacturer Invista on January 1, 2022, the parties announced in separate releases.

“We’re excited for the opportunities that will be made possible by this integration of two of Koch Industries’ chemical businesses,” Jeff Gentry, chairman and CEO of Invista, said in a statement. “Flint Hills Resources’ propylene business complements Invista’s portfolio and will help us accelerate our vision of building a leading polymers and advanced materials company.”

The transfer includes Flint Hills Resources’ chemical facilities in Longview, TX and Houston. Support employees at the locations are expected to join Invista. Ownership of pipelines related to the propylene business will also be transferred to the company, which will be operated by Flint Hills Resources under a contract.

Last month, Invista revealed plans to double the nylon 6,6 capacity of its Invista Nylon Chemicals (China) Co. manufacturing facility in Shanghai, China. The plant will be capable of manufacturing 400,000 tn/yr of nylon 6,6 products. Invista’s expanded capabilities will aid the company in serving demand for engineering plastics in automotive, electrical and electronics, and other applications.
