Product Introduction 
In hydrogen production equipment, PEM sealing gaskets are mainly used for leak-proof sealing in electrolyzers to prevent leakage of hydrogen, oxygen, and liquid electrolytes, ensuring efficient operation of the electrolyzer and preventing safety hazards.
Product Performance
High Oxidation Resistance: It can remain in a high potential and oxygen environment for a long time, maintaining stable performance.
High Acid Resistance: It is not easily corroded in an acidic environment to ensure sealing effect.
Good Temperature Resistance: It can withstand high temperatures above 120℃.
Hydrolysis Resistance: It is not easy to undergo hydrolysis reaction in a saturated water vapor environment for a long time.
Low Eluents: Eluents have little impact on the membrane and catalyst in the PEM electrolyzer.
Good Sealing and Fatigue Resistance: It can adapt to the influence of thermal expansion and pressure changes during the operation of the PEM electrolyzer.
