8.PU聚氨酯橡胶密封圈《Pureurate Resins》

       

Polyamides rubber mechanical properties are very good, O ring manufacturers, high pressure performance are far better than other rubber. Aging resistance, anti-Ozonation, oil resistance is also quite good, but high temperature easy to hydrolyze. Generally used for high pressure, O ring manufacturers damage seal links, such as hydraulic pressure. The general use temperature range is -45 ~ 90 °C.

9. 金属橡胶密封圈《metal rubber sealing ring》

    

Made of non-rusted steel wire, does not contain any rubber components, with strong use characteristics. For example: in high vacuum, high and low temperature, strong radiation, and a variety of corrosive environments to maintain normal operation. Sealing ring skin according to different uses by different materials such as stainless steel, copper, polytetrafluoroethylene and other materials, was coated metal rubber components as lining core, with high sealing strength, the effect of hao, can be reused and so on. The sealing ring core is a component made of different metal wire diameters and densities, which is suitable for different occasions. The general use range is -80 ~ 800 °C. This kind of seal ring is expensive because of its high cost. But good performance, a wide range of use of the environment, have been recognizedby people.
