Styrene-Petrochemicals Market Report 2026

The styrene-petrochemicals market size has grown steadily in recent years. It will grow from $68.27 billion in 2025 to $70.9 billion in 2026 at a compound annual growth rate (CAGR) of 3.8%. The growth in the historic period can be attributed to growth of plastics manufacturing, expansion of consumer goods production, adoption of styrenics in automotive, demand for insulation materials, petrochemical industry expansion.

The styrene-petrochemicals market size is expected to see strong growth in the next few years. It will grow to $86.36 billion in 2030 at a compound annual growth rate (CAGR) of 5.1%. The growth in the forecast period can be attributed to rising automotive lightweighting demand, growth of construction insulation materials, expansion of packaging applications, investment in petrochemical capacity, innovation in styrene copolymers. Major trends in the forecast period include growing demand for abs plastics, rising use in lightweight automotive components, expansion of eps in construction, increased adoption in consumer goods, focus on high impact polymers.

The growing construction industry is expected to drive the expansion of the styrene-petrochemicals market going forward. Construction involves planning, designing, assembling, and building physical structures, facilities, or infrastructure. In this sector, styrene-petrochemicals are used for thermal insulation in buildings, the production of insulated panels for walls and roofs, and flooring applications. For example, in February 2025, according to Eurostat, a Luxembourg-based EU statistical office, construction production remained stable in the euro area and increased by 0.4% in the EU. Compared with the previous month, production in construction grew by 0.6% in the euro area and 0.8% in the EU. Therefore, ongoing construction activity is supporting the growth of the styrene-petrochemicals market.

Major companies operating in the styrene butadiene rubber (SBR) market are focusing on innovative products, such as expanded polystyrene (EPS) made from 50% post-consumer recycled (PCR) content, to drive market revenues. Incorporating PCR content into EPS supports sustainability by reducing demand for virgin raw materials, conserving resources, and diverting plastic waste from landfills. For instance, in April 2023, Epsilyte LLC, a US-based advanced materials provider for construction, launched 124LR expandable polystyrene (EPS). 124LR is designed for molded pieces requiring a smooth finish and is specifically intended for packaging applications. The product contains at least 50% PCR material while performing on par with reactor-made virgin EPS.

In May 2023, Teknor Apex, a US-based plastics compounding company, partnered with UBQ Materials to advance sustainable polymers through waste-to-plastic innovation. The collaboration aims to incorporate UBQ’s waste-derived thermoplastic into styrene-based polymers, promoting sustainable material solutions in industrial and consumer products. UBQ Materials, an Israel-based company, specializes in converting unsorted household waste into thermoplastic materials suitable for integration into polymers such as polystyrene.
