Ammonium Bromide, also known as sal ammoniac, is a white crystalline powder used in the chemical industry as a source of bromine. It is also used in the production of catalysts, in the manufacture of photographic paper, and in the dyeing of textiles.
Common types of rubber failure when exposed to ammonium bromide include swelling, erosion, cracking, and discoloration. Swelling is caused by the rubber absorbing the ammonium bromide, which increases the volume of the rubber and makes it more brittle. Erosion is caused by the chemical reaction between the ammonium bromide and the rubber, which can cause the rubber to wear away. Cracking occurs when the rubber expands and contracts due to the ammonium bromide, causing cracks to form. Discoloration is caused by the chemical reaction between the ammonium bromide and the rubber, which can cause the rubber to turn yellow or brown.
