Ammonia, or anhydrous liquid ammonia, is a colorless and highly pungent gas. It is used in the production of fertilizers, household cleaners, and industrial products. It is also used in refrigeration, cold storage, and cooling systems.
Exposure to ammonia can cause rubber to become brittle and crack. High concentrations of ammonia can cause rubber to swell, weaken, and become brittle. It can also lead to cracking, crazing, and discoloration of rubber surfaces. Ammonia can also cause rubber to lose its elasticity, leading to permanent deformation. Additionally, ammonia can cause rubber to become more susceptible to ozone cracking.
