POTASSIUM CHLORIDE Resistant O-Rings and Seals
Potassium chloride, also known as sylvite, is a naturally occurring mineral salt. It is widely used in the medical, food, and fertilizer industries. In the medical industry, it is used as an electrolyte to treat low levels of potassium in the blood. In the food industry, it is used as a preservative, flavoring agent, and nutrient supplement. In the fertilizer industry, it is used as a source of potassium.
When exposed to potassium chloride, rubber materials may experience swelling, cracking, and hardening due to corrosion. Natural rubber, EPDM, and neoprene rubbers are particularly vulnerable to the chemical and may experience significant degradation in a short time. Nitrile, silicone, and fluorocarbon rubbers may be more resistant to the chemical and remain unaffected. The severity of the failure depends on the type of rubber, the concentration of the chemical, and the length of exposure.
