SILICIC ACID, AQUEOUS Resistant O-Rings and Seals
Silicic acid, also referred to as silicate esters, is a common chemical compound used in a variety of industries. It is often used as a preservative in food, in water treatment to reduce hardness, and as a corrosion inhibitor in industrial processes. Common uses also include the production of detergents, adhesives, and lubricants.
When rubber is exposed to silicic acid, the most common type of failure is the dissolution of the rubber. This is due to the acid’s ability to break down the polymer chains in the rubber, leading to a loss of elasticity. Additionally, the acid can also cause staining, weakening, discoloration, and even softening of the rubber. As a result, rubber that is exposed to silicic acid for extended periods of time can become brittle and more prone to cracking.
