Because of the good elasticity of gas and large thermal expansion coefficient, the bubble gasket has better elasticity than solid seal ring. In addition, it can make sealing ring with different elastic and thermal expansion coefficient by controlling bubble size and distribution density in manufacturing, so as to meet different sealing conditions. Even if the bubble wall is damaged, the new sealing ring will not affect the sealing effect, and overcome the disadvantage of the poor anti-damage ability of the tubular cavity type and avoid the complex structure of the skeleton type. Because of the high thermal expansion coefficient of the foam rubber sealing ring, it is especially suitable for the sealing with temperature rise. Taking the household electric pressure cooker as an example, the bubble gasket has better convenience, sealing and durability. Because the bubble in the rubber ring can expand greatly when the temperature rises, and it shrinks greatly when cooling. This expansion shrinkage state just matches the characteristics of pressure cooker sealing when the temperature rises, and the opening and closing characteristics are convenient for cooling. In addition, due to the filling of bubbles, the manufacture of foam sealing ring is more material saving than the manufacture of solid sealing ring of the same volume.
