Sulfuric acid, 20% oleum, is a concentrated form of sulfuric acid, composed of 20% sulfuric acid and 80% water. It is widely used in industrial processes, such as the production of fertilizers, detergents, dyes and explosives. Additionally, sulfuric acid, 20% oleum, is also used in the manufacture of sulfuric acid, which is essential for many industrial processes, including petroleum refining and metal processing.
When rubber is exposed to sulfuric acid, 20% oleum, it can cause a number of issues, including cracking and discoloration. The chemical can attack and corrode the rubber's molecular structure, leading to the formation of small cracks, as well as discoloration. In addition, the chemical can also lead to a decrease in the material's strength and flexibility, and can increase the rubber's permeability, allowing for the passage of water and other chemicals, which can further damage the rubber.
