AMMONIUM BISULFITE Resistant O-Rings and Seals

Ammonium Bicarbonate, also known as baker's ammonia, is a white, odorless crystalline powder used in the food industry as a leavening agent. It is also used in the pharmaceutical industry as an effervescent and in the glass industry as a source of carbon dioxide for the production of green glass.

Common types of rubber failure when exposed to ammonium bicarbonate include swelling, erosion, cracking, and discoloration. Swelling occurs when the rubber absorbs the ammonium bicarbonate, which increases the volume of the rubber and makes it more brittle. Erosion is caused by the chemical reaction between the ammonium bicarbonate and the rubber, which can cause the rubber to wear away. Cracking occurs when the rubber expands and contracts due to the ammonium bicarbonate, causing cracks to form. Discoloration is caused by the chemical reaction between the ammonium bicarbonate and the rubber, which can cause the rubber to turn yellow or brown.
