Weifang Senya Chemical Co., Ltd.

We are located in a beautiful seaside city-Weifang, Shandong province in China. The city is conveniently connected by all kinds of transportation facilities: ocean shipping, highway, and airfreight.

We are a professional manufacturer in the development and sale of resin and membrane. The ion resin is a synthetic polymer with ionic properties, also called ionomers. The ion-exchange membranes are the most important and key materials of the energy storage batteries and water treatment. We use the modern casting technology and two sides radiation membrane manufacturing technology to produce the ion exchange membrane, we combined the casting technology together with the doping technology, the electrochemical and mechanical properties of our high strength composite perfluoro ion membrane for energy storage battery has achieved or exceeded imported materials.

We have developed and Produced the Ion-Exchange Membrane(IEM) for the Production of Chlorine and Caustic by electrolysis which is environmentally friendly and has become the preferred method for chlorine and caustic production, many of our customers who produce Caustic Soda(NaOH) or Caustic Potassium(KOH) have used our Ion-Exchange Membrane for more than 3 years.

Our Ion-Exchange Membrane(IEM) includes Perfluorinated Ion-Exchange Membrane(PIEM), PTFE Enhanced Perfluorinated IEM, and Homogeneous Ion-Exchange Membrane, the thickness is from 25-550 um with the width from 600mm-3000mm, special size customization is available according to the customer's requirement.

Our Perfluorinated Ion-exchange Resin is widely used as the materials of ion exchange membrane, fuel cell ion membrane, ion exchange membrane for vanadium battery, ion membrane in Chlor-alkali industry, hollow fiber membrane, the super catalyst used in organic synthesis, ultra-stable ion exchanger, and so on.

Our Ion-Exchange Membrane(IEM) is widely used for the production of chlorine and caustic by electrolysis and is used as solid electrolyte membranes in fuel cells, vanadium cells, electrolytic cells, electrodialysis, electrochemical sensors.

Our company has a group of experienced professional staff and technical services staff distributed in various aspects of the workflow. Meanwhile, we have the world's top 500 enterprises supplier chain and value chain management experience, from supplier selection and audit to supplier optimization, cultivation, and development.

Leveraging its advanced manufacturing and technologies, extensive research and development capabilities, we have established a good and stable partnership with many world-known and home enterprises, keep expanding our market and trying to provide one-stop service to our customers so as to minimize their purchase costs.
