Ammonium iodide is also known as sal ammoniac and is a combination of ammonia and hydrogen iodide. It is a white crystalline solid that is used as a reducing agent in chemical syntheses, as a source of iodine in animal feeds, and as a reagent in organic synthesis.
When rubber is exposed to ammonium iodide, the rubber can become hard and brittle. The rubber can also become discolored and the strength of the rubber can be reduced. Additionally, the rubber can become less resistant to heat, oxidation, and ultraviolet light. The rubber can also swell and become distorted, becoming less flexible. Finally, the rubber can become more susceptible to cracking and tearing.
