What material is that high temperature resistant rubber sealing ring, please?
At the same time, high pressure, high temperature resistant, oil resistant sealing ring should be made of fluorine rubber material.
Generally silicone rubber, such as pressure cooker, sealing ring all silicone rubber. Depending on your medium and conditions of use.
Type 246 after aging for 16 hours at 350 DEG C hot air to maintain good elasticity, good elastic aging after 110 minutes at 400 degrees Celsius hot air, hot air aging after 400 degrees in 110 minutes, rubber elongation, thermal spray carbon black containing carbon black or carbon fiber increased by about 1/2~1/3, intensity decreased about 1/2, still maintain good elasticity. Type 23-11 fluoride can be used for 250 years at a temperature of 200 degrees and used for a short period of time.
The high temperature resistance of fluorine rubber is the same as that of silicone rubber. It is the best elastomer in the world at present. 26-41 fluorine glue can be used for 250 years at a temperature of 300 degrees, short-term use; 246 fluorine glue, heat resistance is better than 26-41. In the performance of the aging of 26-41 300 C * 100 hours after the heat and air temperature of 300 DEG C * 100 hours after heat aging type 246, the elongation can be maintained at around 100%, the degree of hardness of 90~95.
