Arlanxeo
HQ SG
Arlanxeo (Singapore; 100% owned by Saudi Aramco since 2018; formerly Lanxess/Saudi Aramco 50/50 JV formed 2016) is a major synthetic rubber producer with EPDM, butyl rubber, nitrile rubber (NBR), and solution styrene-butadiene rubber (S-SBR) product lines. Arlanxeo's EPDM is produced at Geleen, Netherlands (Keltan grades retained under the Lanxess brand after the JV split) and at Triunfo, Brazil. As a Saudi Aramco subsidiary, Arlanxeo has direct access to Saudi petrochemical feedstocks — propylene from Sadara Chemical Company JV (Jubail, Saudi Arabia). Arlanxeo operates manufacturing in Netherlands, Germany, Brazil, Canada, and Belgium. The Saudi Aramco parentage introduces geopolitical considerations: an Aramco-owned company controls EPDM capacity in Europe that supplies automotive and construction supply chains globally.
