AIR, 400 0 500°F, commonly known as atmospheric air, is a mixture of nitrogen, oxygen, and other gases found in Earth's atmosphere. It is used in a variety of industries, including medical, automotive, aerospace, and construction.
When rubber is exposed to air at 400 0 500°F, it can suffer from a number of different types of failure, such as premature cracking and tearing, loss of flexibility, and reduced strength. These types of failure can occur due to the combination of high temperatures and the presence of oxygen, which can lead to the oxidation of the rubber material. This can cause the rubber to become brittle and can lead to cracks and other forms of failure. Additionally, the presence of moisture in the air can cause the rubber to swell, resulting in a decrease in its physical properties.
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.
