The Chinese chemical industry is set to introduce significant new production capacity across multiple major chemical product lines throughout 2026, reflecting sustained investment and plans for scaling industrial output to meet domestic and export demand. The data, published by commodity intelligence provider SunSirs, outlines capacity additions for eight key chemical products across the year.
Record Capacity Growth Across Major Petrochemicals
In 2025, China’s chemical sector achieved historic refining capacity levels — nearly 980 million tons — and will continue this growth trajectory in 2026 as major integrated refining and petrochemical projects come online, accelerating the country’s high‑end industrial transformation.
Polypropylene (PP)
Polypropylene capacity is projected to grow by 5.7 million tons, driving total capacity above the 50‑million‑ton mark for the first time. Most of this expansion is scheduled for the second half of 2026, indicating an acceleration trend in PP production capabilities.
Polyethylene (PE)
Similarly, PE is expected to add about 5.5 million tons of new capacity, expanding total output beyond 45 million tons. The bulk of the new capacity will consist of high‑density variants and full‑density products, with peak commissioning planned later in 2026.
ABS and PS Production Expansion
Adhesive and styrene‑acrylonitrile (ABS) capacity is forecast to increase by nearly 2 million tons, lifting total ABS capacity above 12 million tons. Polystyrene (PS) additions will contribute roughly 1.47 million tons, with a strong focus on key consumption regions such as East China.
New production capacity for PET bottle‑grade chips is set to increase by approximately 1 million tons, bringing the overall PET bottle flake output beyond 22 million tons. This additional capacity is expected to support downstream packaging and textile applications.
Methanol, a critical industrial feedstock — will see a 5.5 million‑ton expansion, driven by major projects and upgrades in integrated coal chemical complexes and refining clusters.
Ethylene Glycol and Other Chemicals
Ethylene glycol production is projected to expand by around 3.33 million tons in 2026, further reinforcing China’s significant position in basic chemical production. This growth is aligned with broader shifts toward petrochemical modernization and integration across product chains.
These capacity expansions signal a robust strategic push within China’s chemical industry toward scale, efficiency, and supply security. As production capabilities increase across these core chemical products, market supply dynamics, both domestically and internationally may adjust, particularly as new output enters later phases of commissioning.
Industry experts note that while rising capacity supports growth and competitive positioning, it also intensifies pressure on the market to balance supply and demand, particularly for commodity chemicals, where inventory and pricing swings can influence global trade patterns.
China’s planned capacity additions for 2026 reinforce its role as a dominant global chemical producer. By expanding production in key materials such as PP, PE, ABS, PET bottle chips, methanol, and ethylene glycol, the sector is poised to support broader industrial growth and export performance in the years ahead.
