POTASSIUM IODIDE Resistant O-Rings and Seals
Potassium iodide, also known as saleratus, is a chemical compound commonly used in food fortification, photography, and as an expectorant. When rubber is exposed to potassium iodide, it can cause discoloration and corrosion of the material, as well as a breakdown of the rubber due to the chemical's hygroscopic properties. Additionally, the presence of iodine in the chemical can cause embrittlement of the rubber over time, resulting in cracks and brittle joints.
