Technip Energies (Paris: TE) and SIBUR Holding Public Joint Stock Company (SIBUR) announced that the companies have signed a collaboration agreement to license a dedicated technology for the production of hexene-1 from ethylene.

Hexene-1 is a comonomer of choice in the production of high-value specialty resins. The incorporation of hexene-1 allows for better end-product properties and contributes to a lower use of carbon for equivalent performance. This novel technology, operating at low pressure and temperatures, has been developed by SIBUR and will be licensed by Technip Energies.

Stan Knez, Chief Technology Officer, Technip Energies, stated “We are very proud to promote this technology which is simple and reliable. This specially developed technology delivers a high quality product, that may be dropped into existing polyethylene production facilities. SIBUR’s HEXSIB technology provides gains in carbon efficiency and opens up possibilities for bio-sourced plastics production from renewable carbon.” 

Daria Borisova, SIBUR Management Team Member, Managing Director of Development and Innovations, said: “The agreement with Technip Energies strengthens the engineering platform of SIBUR's technology and gives us the opportunity to promote it through Technip Energies’ partner network. SIBUR is currently selecting a site within the group's range of facilities for production of hexene-1 with the HEXSIB technology to satisfy its own and the market’s needs as the company expands its portfolio of high value grades and share of comonomers.''
