The operating temperature range of rubber seal is an important parameter. It should not only consider the operating temperature of hot state (high temperature resistance), but also consider the operating temperature of cold state (cooling performance, low temperature resistance).
Rubber rubber seal materials will form different hardness points, hard seal ring can resist extrusion, soft O-ring has lower explosive or sliding friction performance.
The change of the elongation of rubber seal is also the quality mark of elastomer. The elongation is very important for installation, especially when the seal ring size is small.
