The allowable temperature range of mechanical seal materials:

In modern engineering, the temperature range of mechanical seal sealing materials can actually range from ultra-low temperature to over 1227 degrees Celsius (1500K). Of course, for different sealing materials, the sealing performance is also quite different. At low temperatures, the basic requirement for sealing materials is the stability of physical mechanics and thermophysical properties.

For the currently widely used polymer sealing materials, temperature is one of the main factors limiting their wider application. Because the low temperature will harden the polymer sealing material, lose its elasticity and become embrittled. The high temperature will cause creep and stress relaxation of the polymer. For contact type seals, this will reduce the specific pressure of the seal and destroy the stability of the sealing performance.　　256.html,
