New Patent Strengthens Chromis Gas Separation Membrane Platform
Chromis Technologies is pleased to announce the issuance of U.S. Patent No. 12,473,391 on November 18, 2025 for “Gas Separation Articles Composed of Amorphous Fluorinated Copolymers of Dioxolanes and Other Fluorinated Ring Monomers and Methods of Making and Using Thereof.” The patent covers a new class of materials and articles relevant to gas separation membranes and related gas separation system designs.
Why Gas Separation Membranes Matter
Membrane-based gas separation is used commercially in applications such as natural gas processing, hydrogen recovery, nitrogen generation, and biogas upgrading. Public market estimates vary, but recent reports place the global gas separation membrane market in roughly the $1.5 billion to $2.3 billion range, with continued growth projected through the decade. As industry demands separation technologies that can offer energy efficiency, compact system design, and modular operation, material innovation becomes increasingly important.
Building a Broader Platform in Polymeric Membrane Gas Separation
Responding to these challenges, Chromis has been building a broad materials platform around advanced amorphous fluoropolymers for gas separation applications. Our first patent in this field (U.S. Patent No. 12,139,629, issued on November 12, 2024) covered gas permeable windows composed of amorphous crosslinked fluorinated copolymers and methods of making and using them. This most recent patent strengthens our position in the field of polymeric membrane gas separation – where performance depends on the ability to tailor permeability, selectivity, durability, and manufacturability in the same material platform – by protecting gas separation articles based on amorphous fluorinated copolymers incorporating dioxolanes and other fluorinated ring monomers.
Why This New Patent Matters
These patents demonstrate our core ability to design and develop differentiated amorphous fluoropolymer chemistries for demanding applications. We aim to expand the materials toolbox available for gas separation membranes and related systems, opening the door to membrane designs with more tailored selectivity and permeability performance characteristics. Our growing intellectual property portfolio helps support future product development, strategic partnerships, and commercialization opportunities in the broader gas separation systems landscape.

FAQs
How does this latest patent relate to Chromis’ earlier patent activity?
The new patent builds on Chromis’ earlier U.S. Patent No. 12,139,629, titled “Gas Permeable Windows Composed of Amorphous Crosslinked Fluorinated Copolymers and Methods of Making and Using Thereof,” which issued on November 12, 2024. Together, the two patents support a broader platform based on amorphous fluoropolymer materials for gas separation-related applications.
Why do gas separation membranes matter?
Gas separation membranes are important because they can enable selective separation of gases in compact, modular systems used in a range of industrial processes. Their value often depends on the ability of the membrane material to balance permeability, selectivity, chemical resistance, and processability.
Why is polymer chemistry so important in membrane gas separation?
Because the membrane material largely determines how well the system performs. Improvements in polymer design can help create membranes with more useful combinations of transport behavior, stability, and manufacturability.
What is the broader significance of this patent?
The broader significance is that it strengthens Chromis’ intellectual property position around advanced amorphous fluoropolymers and supports the company’s long-term effort to build a differentiated materials platform for gas separation technologies.
Does Chromis manufacture membranes?
No. Chromis develops and supplies the selective polymer coatings that are applied to membrane substrates. These materials are designed to work as the active layer in flat-sheet, hollow-fiber, or other membrane formats made by our partners.
