 Applications 

1. For Oilfield Completion And Workover Fluids: Zinc bromide (ZnBr2, CAS 7699-45-8) is used to formulate high-density, solids-free clear brine fluids for well completion, workover and drilling mud displacement, helping operators control formation pressure and maintain wellbore stability in demanding oil and gas operations.

2. For Zinc-Bromine Flow Batteries: As the active electrolyte component in zinc-bromine redox flow batteries, zinc bromide supports energy storage systems for grid and industrial applications, where high solubility and stable electrochemical performance matter.

3. For Organic Synthesis And Catalysis: Zinc bromide acts as a Lewis acid catalyst in organic synthesis, supporting stereo-selective and regio-selective reactions in the production of fine chemicals and specialty intermediates.

4. For Radiation Shielding: High-concentration transparent zinc bromide solutions are used as shielding liquids in hot cell observation windows and radiation shielding applications in nuclear facilities, offering high density and optical clarity without permanent darkening under radiation.

5. For Photographic And Laboratory Applications: Zinc bromide is used in photographic emulsions, synthetic fiber after-treatment and as a laboratory analytical reagent, giving industrial and research users a versatile zinc salt for specialty applications.

 Quality Assurance 

Every batch of chemicals leaves our factory with complete laboratory documentation — not a promise, but verifiable test data. From incoming raw material inspection to finished-goods release, each batch is tested against published specifications, and a Certificate of Analysis (COA) accompanies every single shipment. What you order is exactly what we test — and what we ship.

Tested by our in-house ISO 9001:2015 laboratory. Verified independently by third-party labs on request (SGS / BV / Intertek). Traceable from raw material to your warehouse.
