Styrene Monomer Market Valuation Forecasted to Reach USD 80.4 Billion by 2034
Shell plc, a global energy company, is currently conducting a strategic review of its chemicals division, including its styrene monomer operations, to enhance operational efficiency and profitability. This move comes as the global Styrene Monomer market is projected to reach an impressive size by 2034.
According to market projections, the projected size of the global Styrene Monomer market by 2034 is estimated to be USD 184.72 billion, with an expected Compound Annual Growth Rate (CAGR) of 6.45% from 2025 to 2034. This forecast is based on styrenics market data, which includes styrene monomer as a significant product within the styrenics segment.
The Asia Pacific region currently dominates the market, holding a 47.5% share in 2024. The market's growth is projected at a CAGR of 5.4% from 2025 to 2034.
Styrene monomer is essential in producing packaging materials like polystyrene foam and clear plastic film for food containers, trays, and protective packaging. It is also used in household items such as appliance housings, toys, disposable tableware, and consumer electronics enclosures due to its ease of molding, glossy finish, and affordability. Moreover, styrene monomer is used in automotive components such as ABS and SBR plastics for bumper covers, interior trims, and dashboards.
In addition, styrene-based foams like EPS and XPS are widely used in building insulation panels, structural forms, and pipes for thermal efficiency, moisture resistance, and structural support.
The global styrene monomer market saw significant developments in 2024. For instance, the packaging sector held the largest end-use share in the market at 27.1%. Polystyrene led the styrene monomer market by application in 2024, representing 42.9% of total consumption.
Notable events in 2024 include Westlake Corporation restarting its styrene monomer unit in Louisiana and joining an anti-dumping complaint with other epoxy resin producers against Asian imports into the EU. SABIC's Cos‐Mar styrene monomer unit in Louisiana also achieved ISCC PLUS certification in 2024, allowing for the commercialization of circular-or bio-renewable styrene monomer.
Meanwhile, the Middle East & Africa and Latin America showed moderate growth in the styrene monomer market, driven by infrastructure development and increasing demand for consumer goods. However, regulatory pressures to reduce plastic waste may pose a growth challenge.
In India, domestic styrene demand is expected to grow by 15% in FY2025-26. Indian Oil Corporation Limited (IOCL) is setting up a domestic styrene monomer production facility in India with a capacity of 387 thousand tonnes.
On the other hand, INEOS Styrolution announced the permanent closure of its styrene monomer plant in Sarnia, Ontario by June 2026, citing regulatory constraints and economic non-viability.
The styrenics market's growth is driven by the rising demand from the electric vehicle and electronics sectors due to styrene's properties such as lightweight, heat resistance, and strength. However, the challenge of reducing plastic waste remains a concern.
