Kunshan thermal pad factor

In the use of gaskets in Kunshan Thermal Gaskets, both pressure and temperature are mutually restrictive. As the temperature rises, after the equipment is operated for a period of time, the gasket material undergoes softening, creep, stress relaxation, and mechanical strength. It will also fall, and the pressure of the seal will decrease. vice versa. For example, the manual lists high-pressure asbestos rubber sheet XB450 in water and steam medium at a temperature of 450°C and a pressure of less than 6 MPa (When the material is used for sealing performance test, pressure is maintained at 440°C-450°C and 12 MPa steam for 30 minutes) . However, in the long-term practical use, if the temperature reaches 450 °C, the sealable pressure is only 0.3 ~ 0.4MPa. For highly permeable gas media, it is only 0.1 to 0.2 MPa.

(1) It has good elasticity and recovery and can adapt to pressure changes and temperature fluctuations;

(2) With appropriate softness, it can fit well with the contact surface;

(3) does not pollute the process media;

(4) Have sufficient toughness without breaking the ring due to pressure and tightening force;

(5) It does not harden at low temperatures and has a small shrinkage;

(6) Good processing performance, convenient installation and compaction;

(7) It does not adhere to the sealing surface and it is easy to remove;

(8) The price is cheap and the service life is long.
