CHROMIUM POTASSIUM SULFATE Resistant O-Rings and Seals
Chromium Potassium Sulfate, also known as Chromium Potash Sulfate, is an inorganic compound composed of chromium, potassium, and sulfur. It is a colorless or yellow-white crystalline solid that is used primarily as an additive in cement, as well as a mordant in dyeing and tanning. It is also used in the production of inks, pigments, and fertilizer.
When rubber is exposed to Chromium Potassium Sulfate, it can lead to the softening and swelling of the rubber, making it more prone to cracking and seal failure. The compound can also corrode metal parts, causing further damage to the rubber components. Prolonged exposure can lead to a complete breakdown of the rubber, resulting in a loss of elasticity and a decrease in strength.
