The U.S. Phthalic Anhydride Market was valued at USD 0.68 billion in 2025 and is expected to reach USD 0.97 billion by 2035, growing at a CAGR of 3.59%.
The well-established PVC compounding industry, ongoing demand from the paints and coatings industry, and an active alkyd resin manufacturing base supporting the production of architectural and industrial coatings are the main drivers of the mature but stable phthalic anhydride market in the U.S.
Rising Demand from Construction and Paints & Coatings Industries to Drive Market Growth Globally
The primary growth driver for the phthalic anhydride market share is rising demand from the construction and paints and coatings industries. This is fueled by rising infrastructure development spending in Asia Pacific and Latin America, growing use of unsaturated polyester resins in construction composites, and rising consumption of alkyd resins in architectural coatings. The market’s foundation, the penetration of flake and molten phthalic anhydride product forms, and the growth of the global market share are all being driven by these applications for surface protection and structural material enhancement.
Segmentation Analysis:
By Technology
The orthoxylene (OX) process segment accounted for the highest revenue share of approximately 78.34% in 2025, owing to the widespread availability of orthoxylene as a petrochemical co-product, higher selectivity and yield efficiency in vapor-phase catalytic oxidation. The naphthalene process segment is anticipated to achieve the highest CAGR of nearly 4.28% during the 2026–2035 period, driven by the continued operation of legacy naphthalene-based production assets in Eastern Europe and China.
By Form
The molten phthalic anhydride segment contributed the largest revenue share of approximately 61.47% in 2025 due to its direct usability in downstream plasticizer and resin manufacturing. The flake segment is projected to maintain steady demand with moderate growth throughout 2026 to 2035 due to the growing need for transportable product forms suitable for smaller batch processors globally.
By Application
The phthalate plasticizers segment accounted for the largest application share of approximately 44.62% in 2025, owing to the extensive use of DEHP, DINP, and DIDP plasticizers in flexible PVC production. The unsaturated polyester resins segment is slated to grow at the fastest rate with a CAGR of around 4.71% 2026–2035, as construction activity, marine vessel manufacturing, and wind energy composite fabrication drive consistent volume offtake from phthalic anhydride producers supplying the UPR industry.
By End-Use
The construction segment accounted for the largest end-use share of the phthalic anhydride market with about 27.18% and is also expected to grow at the fastest rate with a CAGR of around 4.53% throughout the forecast period of 2026–2035. The segment’s growth is driven by extensive consumption of alkyd resin-based architectural coatings, UPR-based construction composites, and PVC-based building materials including pipes, window profiles, and roofing membranes across residential and commercial building sectors globally.
