COPPER SULFATE Resistant O-Rings and Seals
Copper sulfate, also known as cupric sulfate, is a common chemical used in a variety of industries such as agriculture, water treatment, and textiles. It is used in agriculture as a fungicide and pesticide, in water treatment to control algae, and in textile manufacturing to treat rust and dye fabrics.
When rubber is exposed to copper sulfate, the rubber material can become brittle and crack. This is mainly due to the sulfuric acid that is produced when copper sulfate is dissolved in water. The sulfuric acid can penetrate the rubber and cause it to oxidize and become brittle. Additionally, copper sulfate can cause discoloration and staining of the rubber material.
