The global propylene market has posted steady growth in recent years and is forecasted to grow significantly at a CAGR of 2.4% over 2026 to 2030. Polypropylene, a thermoplastic polymer of propylene, accounts for over 70% of propylene’s end use globally, as it finds extensive application in consumer goods, automotive parts, packaging, and high-value new materials. China remains the undisputed leader of this global growth, set to dominate global propylene demand while outpacing every other country by a substantial margin.

In 2026, China is likely to witness a demand of 67.37 million tonnes per annum (mtpa), accounting for over 45% of global propylene demand. This dominance of China in global propylene demand is attributed to the country’s massive manufacturing sector, rapid urbanisation, and surging middle class, fuelling the strong consumption of polypropylene and other propylene derivatives.

Moreover, China’s aggressive investments in propylene production capacity—especially through the proliferation of modern propane dehydrogenation (PDH) plants—reinforce its drive for self-sufficiency and position it as both a consumption and production powerhouse not only in 2026 but through the end of the decade.

Following China, the US and India remain significant contributors to global propylene demand. In 2026, the US is expected to register a demand of 16.12mtpa, driven by cost-advantaged shale gas and the steady growth of the packaging and automotive industries. Meanwhile, India’s propylene demand this year is likely to be at 8.06mtpa, powered by the fast-paced industrialisation, high population growth, and government initiatives targeting manufacturing capacity.
