Ammonium Chloride is also known as sal ammoniac or ammonium muriate and is a white crystalline salt commonly used as a food additive, an agricultural fertilizer, a flux in metallurgy and a fireproofing agent. Common uses include in the production of batteries, fireworks and pigments, as a curing agent for leather and as an electrolyte in electrolytic cells.
When rubber is exposed to Ammonium Chloride, it is prone to cracking and brittleness due to the acidity of the compound. Over time, the rubber may become brittle and crack, leading to failure of the seal or other rubber part. Additionally, the compound can cause softening and swelling of the rubber, leading to a decrease in strength and an increase in permeability, allowing fluids to pass through.
