Key Players
Competitive Landscape
BASF leads the engineering plastics market at 15% to 19%, followed by DuPont at 12% to 16%, Covestro at 10% to 14%, LG Chem at 8% to 12% and Arkema Group at 6% to 10%. Other companies hold 35% to 45% together. Asahi Kasei, Celanese, DSM N.V., Lanxess and Mitsubishi Engineering-Plastics round out the group of key producers.
Supplier footprints changed through 2025 and 2026. Polyplastics reported POM and COC additions, Arkema announced a transparent polyamide unit, and Celanese closed the Ulsan compounding facility.[1][2][5] Victrex impaired the Panjin plant, and China set duties on POM copolymer imports.[6][4] Delivered capacity now separates suppliers more than announced tonnes do.
Company developments mapped to drivers, trends and opportunities (2026-2036)
| Development | Driver | Trend | Opportunity |
|---|---|---|---|
| Second quarter 2026: Celanese completed the Ulsan compounding closure and the nylon 6,6 network optimisation. | Higher raw material costs in Engineered Materials were named as a third-quarter headwind. | Compounding and nylon 6,6 footprints are being consolidated. | Suppliers with qualified grades can serve customers moved out of Ulsan. |
| May 2026: Victrex booked a GBP 60.6 million impairment on the Panjin plant. | The plant is not capable of the full intended nameplate capacity of 1,500 tonnes. | New plants can ramp slower than announced. | Suppliers with proven output can secure approvals at buyers waiting for supply. |
| October 2025: Polyplastics updated the POM, COC and LCP additions. | POM Phase 1 of 90,000 tons a year and Phase 2 of 60,000 tons in fiscal year 2027. | Specialty capacity is being added in China and Germany. | Buyers can qualify second sources ahead of Phase 2. |
| May 2025: Reuters reported China duties on POM copolymer of up to 74.9%. | Rates differ by origin and by company. | Import supply into China is repriced. | Plants inside China gain a cost position against duty-paid imports. |

Celanese is consolidating compounding and nylon 6,6 sites, Polyplastics is adding POM and COC lines, and Victrex is working through a ramp-up shortfall at Panjin. The three companies differ by polymer, region and stage of the capacity cycle.
Who leads the engineering plastics market?
BASF holds the highest share at 15% to 19%, followed by DuPont at 12% to 16% and Covestro at 10% to 14%. LG Chem and Arkema Group follow at 8% to 12% and 6% to 10%. Leadership will follow qualified grades and plant output, not announced tonnage.
Which companies are changing capacity?
Polyplastics plans 150,000 tons a year of POM at Nantong once Phase 2 is complete.[1] Arkema plans to triple global Rilsan Clear capacity at the Singapore platform.[2] Celanese completed the Ulsan compounding closure in the second quarter of 2026.[5] Victrex expects around 100 tonnes of sales from Panjin in fiscal 2026 against a nameplate of 1,500 tonnes.[6]
What should buyers evaluate before approving a supplier?
Buyers first check whether announced tonnes have been delivered, as the Victrex Panjin plant has not reached nameplate capacity.[6] The plant of origin for each grade comes next, since Celanese closed the Ulsan compounding facility.[5] Duty status completes the check for POM copolymer shipped into China, with rates of up to 74.9%.[4]
How is competition expected to change through 2036?
Competition is moving from announced tonnes to delivered output and portfolio focus. DuPont has sold Aramids and divested Delrin, and Celanese has consolidated compounding and nylon 6,6 sites.[8][5] New specialty capacity from Polyplastics and Arkema targets POM, COC and transparent polyamide.[1][2] Polyamides and automotive lead 2026 sales, so rivalry tightens first in automotive grades.
