Domestic polypropylene output in 2025 maintained the growth momentum seen since 2024, with total annual production surpassing 39 million metric tons—a year-on-year increase of 14%. This growth rate significantly outpaced the 7% recorded in 2024, setting a new high in recent years.
This production surge reflects profound shifts in China's polypropylene industry landscape. Monthly data shows consistent output above 3 million tons throughout 2025, with some months nearing 3.5 million tons—generally exceeding 2024 levels by 300,000 to 480,000 tons. This growth primarily stemmed from the concentrated release of new capacity. Total new capacity additions in 2025 reached 5.355 million tons, with the commissioning of large-scale facilities like Yulong Chemical, Daqiao Petrochemical, and ExxonMobil Huizhou directly driving the substantial production surge.
Amidst this high production growth, the divergence in growth rates across product categories became increasingly pronounced. General-purpose grades, particularly filament grades, became the main growth driver. New facilities in 2025, such as Ningbo Daxie and Guangxi Petrochemical, directly boosted general-purpose grade output, achieving an annual growth rate of 17%. Support from essential markets like plastic weaving and packaging significantly enhanced the supply elasticity of filament grades. Impact-modified copolymers also emerged as a major growth category for polypropylene. With their notable impact resistance and suitability for modification, they are increasingly adopted. The rapid development of new energy vehicles and home appliances has driven growth in copolymer products, with a year-on-year growth rate of 13.45% in 2025. Other categories also saw varying degrees of increase.
Looking ahead, the polypropylene industry is undergoing a critical period of structural adjustment. With over 5 million tons of new capacity expected to come online in 2026, supply pressure may persist, but the proportion of high-end specialty grades is anticipated to increase. Industry players are accelerating their shift toward high-end products, with modified materials and automotive lightweighting materials becoming strategic priorities. This not only helps alleviate oversupply pressures in commodity grades but also propels the sector toward high-quality development. Through sustained expansion in export markets, China's polypropylene industry is poised to gradually establish a more resilient development framework amid supply-demand rebalancing.
