Ferric chloride, also known as iron chloride, is an inorganic compound used in many industries, including water treatment, the production of pigments, and in the production of other chemicals. It is also used in the etching of printed circuit boards, as well as in electroplating and other metal finishing processes.
When rubber is exposed to ferric chloride, it can cause swelling and softening of the material, resulting in a decrease in tensile strength and an increase in brittleness. This can lead to cracking and eventual failure of the rubber. Additionally, the compound can cause corrosion of the rubber, leading to discoloration and further weakening of the material. To prevent these issues, it is important to use rubber materials that are resistant to the effects of ferric chloride, such as nitrile rubber, butyl rubber, and fluorosilicone.
