Company Profile

CAS-Realnm is dedicated to the design, R&D, production, sales, and technical service of advanced functional materials. Leveraging proprietary surface modification technologies, we precisely control the surface energy, roughness, and porosity of polymers to develop a full portfolio of oil-water and oil-gas separation materials. These materials deliver high-efficiency, high-purity separation performance across liquids, gases, and other demanding applications.

Our product portfolio comprises six series of functional materials—demulsification, hydrophilic, oleophilic, amphiphobic, antibacterial, and customized types—along with a standardized separation process (AIS: Aggregation-Induced Separation), which we have independently developed and widely adopted in the industry.

Backed by years of research and application, CAS-Realnm products are trusted in diverse industries worldwide, including:

• Transportation: fuel, engine oil, and urea filter materials, as well as other oil-water and oil-gas separation filters.

• Energy & Resources: oilfield reinjection water treatment, refining emulsified oil separation, organic reagent dehydration, and Separation of catalyst poisoning cleaning mixtures.

• Industrial Filtration: inlet gas, exhaust gas, circulating and discharged water treatment.

At CAS-Realnm, focus creates expertise. With this commitment, we strive to build long-term, stable, and mutually beneficial partnerships with downstream application industries, creating sustainable value together.
