EPDM rubber seals & gaskets

Swedish polymer-engineering group; Trelleborg Sealing Solutions is a global leader in O-rings, seals and gaskets for industrial, aerospace and medical use.

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.

Dow Inc. (Midland, Michigan; NYSE: DOW; ~$45B revenue) is a major global EPDM producer through its Performance Elastomers division, producing NORDEL EPDM. NORDEL is manufactured primarily at Dow's Freeport, Texas complex (one of the largest integrated chemical sites in North America) and at European facilities. NORDEL EPDM is used in automotive weatherstripping, roofing, wire insulation, and plumbing seals. Dow is estimated to hold ~15-18% of global EPDM capacity. The NORDEL brand has been a benchmark EPDM product since the 1960s (originally DuPont, transferred to Dow in 2019 DuPont-Dow merger split). Dow's integrated Freeport site gives it ethylene and propylene feedstock advantages for EPDM production cost.

ExxonMobil Chemical Company (Spring, Texas; NYSE: XOM; chemical segment ~$12B revenue) produces Vistalon EPDM at its Baton Rouge, Louisiana and Baytown, Texas complexes — two of the world's largest integrated petrochemical sites. Vistalon EPDM holds an estimated 12-15% global market share. ExxonMobil's ethylene and propylene feedstock integration at its Gulf Coast facilities provides a cost structure advantage for EPDM production. Vistalon is used in automotive seals, roofing membranes, wire insulation, and plumbing and water system gaskets. ExxonMobil also produces Butyl rubber (Butyl IIR) and other specialty elastomers from the same Gulf Coast facilities — the same sites producing vehicle fuel also produce the rubber seals used in plumbing systems.

Diversified motion and control technologies company (NYSE: PH); Cleveland, Ohio. World's largest motion and control technology manufacturer. Hydraulics Group produces axial piston pumps and motors, gear pumps, vane pumps, cylinders, valves, and hose assemblies for agricultural, construction, industrial, and aerospace markets. One of four companies that collectively held >60% of global hydraulic motors market (2018). Agricultural customers: John Deere, CNH Industrial, AGCO, Kubota — all major OEMs. Key ag hydraulics facilities: Wooster, Ohio (cylinder manufacturing); Columbus, Indiana; multiple global plants. FY2024 revenue: ~$20B; Aerospace Systems and Industrial segments larger than Hydraulics, which was spun into Motion Systems segment.
