AMMONIA GAS, HOT Resistant O-Rings and Seals
Ammonia gas, hot (also known as aqueous ammonia) is a colorless, pungent gas that is commonly used in industrial cleaning processes. It is also used in the production of fertilizers, plastics, and other chemicals.
When rubber is exposed to ammonia gas, hot it can cause softening, cracking, and other forms of physical damage. This is due to the ammonia's ability to break down the chemical bonds between the rubber molecules, making the rubber more malleable and prone to physical damage. Additionally, the hot temperature of the ammonia can cause corrosion and oxidation of the rubber, leading to further degradation of the material.
Silicone (VMQ, SIL)
Silicone o-rings are excellent seal materials for high temperatures in static environments. Typically, silicone o-rings show outstanding flex and fatigue life, strong ozone and UV radiation resistance, and physiologically neutral and insulating properties. Silicone o-rings can be synthesized with a wide variety of properties and compositions, allowing for great flexibility in performance.
