SODIUM, MOLTEN Resistant O-Rings and Seals

Sodium, also known as sodium metal, is a soft, silvery-white metal commonly used in a variety of industrial and consumer applications. It is used in the production of sodium hydroxide, chlorine, and sodium bicarbonate, and is also used in the production of automobile and aircraft parts, as well as sodium-based detergents.

When rubber is exposed to molten sodium, it can suffer from accelerated degradation due to the chemical's highly reactive nature. The sodium can react with the rubber material, causing it to become brittle, discolored, and swell. In addition, the sodium can cause cracking and embrittlement of the rubber, resulting in a decreased lifespan of the rubber product. Furthermore, the sodium can cause the rubber to oxidize, resulting in decreased strength and elasticity.
