ALUMINUM FLUORIDE Resistant O-Rings and Seals
Aluminum Fluoride, also known as AlF3, is a chemical compound composed of one atom of aluminum and three atoms of fluoride. It is commonly used in aluminum production, as a catalyst in chemical reactions, and in the manufacture of glass, ceramics, and rubber products.
When rubber is exposed to Aluminum Fluoride, the rubber can become brittle and crack due to the chemical reaction between the aluminum and the fluoride. Aluminum Fluoride can also cause the rubber to swell, which can lead to cracks, leaks, and other forms of physical damage. In extreme cases, the rubber can become so brittle that it breaks apart. To prevent these types of failures, it is important to select the right type of rubber for the application and to keep the rubber away from Aluminum Fluoride as much as possible.
