Sal Ammoniac, also known as Ammonium Chloride, is a white, crystalline solid. It is used in a variety of industries, such as in fire extinguishers, as a food additive, in leather tanning and dyeing, and in the production of fertilizers and explosives. It is also used in the production of ammonia gas, for cleaning stainless steel, and in various medical and laboratory applications.
When rubber is exposed to Sal Ammoniac, it can suffer from a variety of issues, including discoloration, cracking, and softening. In extreme cases, the rubber can become brittle and break. Additionally, when exposed to high concentrations of Sal Ammoniac, the rubber can become brittle and swell, which can lead to failure of the rubber seal.
