Is urea solution resistant to nitrile rubber?
Urea solution is corrosive to nitrile rubber, and long-term exposure may destroy the function of nitrile rubber. Therefore, urea solution is not resistant to nitrile rubber. .
Urea solutions of various concentrations will not react or corrode with many types of rubber. It can be used as long as it is at the temperature allowed by the type of rubber.
Urea will hydrolyze to form ammonia, and the ammonia solution will be alkaline, causing the cyano group of nitrile rubber to hydrolyze. Therefore, there is no problem with short-term contact ； Long-term contact may weaken the effect of rubber.
Don’t forget that urea and water are found in human and mammalian urine. After decades of use, there has been no human body corrosion problem. Urea and ammonia will also form if sweaty feet are not washed for a long time, and there is no corrosion problem in rubber-soled Jiefang shoes. The above questions are pure nonsense.
