Top 10 Companies in the DMAc Dimethylacetamide Polyimide Membrane Casting Solvent Market (2026): Market Leaders Powering Global Growth

MARKET INSIGHTS

Global DMAc Dimethylacetamide Polyimide Membrane Casting Solvent Market size was valued at USD 320.4 million in 2025. The market is projected to grow from USD 338.6 million in 2026 to USD 562.8 million by 2034, exhibiting a CAGR of 6.5% during the forecast period.

Dimethylacetamide (DMAc) is a high‑boiling, polar aprotic solvent widely recognized as one of the most effective casting solvents for polyimide membrane fabrication. Its exceptional solvating power, thermal stability, and compatibility with high‑performance polymers make it indispensable in the production of asymmetric and composite membranes used across gas separation, water treatment, and pharmaceutical filtration applications. DMAc enables uniform polymer dissolution and precise control over membrane morphology during the phase inversion casting process, which is critical to achieving desired permeability and selectivity characteristics.

The market is gaining momentum driven by the rapid expansion of polyimide membrane demand in gas separation technologies, particularly for hydrogen purification and carbon capture applications. Furthermore, the growing adoption of advanced filtration membranes in the semiconductor and electronics industries is reinforcing DMAc consumption. Key producers operating in this space include BASF SE, Eastman Chemical Company, and Zhejiang Jiuzhou Pharmaceutical Co., Ltd., among others, each maintaining broad product portfolios catering to high‑purity industrial solvent requirements.
