Nafion™ membranes for chlorine and caustic soda production

　　Chlorine (Cl2) and sodium hydroxide (NaOH) are common chemicals produced in large quantities throughout the world. However, the industry has used inefficient processes that pose safety risks to workers and damage the environment for years. These methods use mercury or asbestos diaphragm cells to transfer sodium ions between half cells.

　　Modern methods use cation exchange membranes between half cells to produce Cl2 and NaOH by salt water electrolysis, which helps to solve the safety issues that caused by the old process in the production of chlorine and sodium hydroxide.

　　Nafion™ membranes are ideal for industrial applications because they withstand the high temperature, high current and corrosive environment of the electrochemical cells used in this process. These membranes can also be used in the potassium hydroxide process.

　　In addition, the characteristics of Nafion™ membranes include:

　　Supports cation transfer at very low resistance;

　　Prevent the formation of gas mixing;

　　The Cl− and OH− ion rotation is greatly reduced;

　　Produce high quality products.
