FLUOROSILICIC ACID Resistant O-Rings and Seals

Fluorosilicic acid is also known as hexafluorosilicic acid and is widely used in water fluoridation, as well as in the production of fertilizers, glass, and ceramics. In the industrial sector, it is used as a cleaning agent, to etch metal surfaces, and to produce aluminum and magnesium.

Common types of failures when rubber is exposed to Fluorosilicic acid include discoloration, cracking, and weakening of the rubber. The acid can also cause the rubber to become brittle and may cause the rubber to become sticky, leading to adhesion and sticking to other surfaces. Additionally, prolonged exposure to Fluorosilicic acid can lead to the rubber breaking down over time.
