How to buy rubber shock absorbers?

What do you need to pay attention to when buying rubber shock absorbers?
 
To fully understand the performance characteristics of the shock absorber, follow the use of different environments to choose. Rubber is very flexible and light in texture, so you need to pay attention to the environment in which rubber-based vibration damping products are used.
 
 Damping spring shock absorber itself has an incomparable sealing, and no matter how it is compressed, it only undergoes elastic deformation, and its own volume is almost no change. If it is in a hydraulic environment, there is no better choice than to play the role of vibration damping, but also to seal and not to let the liquid spill. Rubber can also be resistant to corrosion, if it is in some serious corrosion of the harsh environment, such as many chemical plants, such as the production plant, these places need vibration damping device, it is recommended to use rubber vibration damper.
 
Due to the qualities of the product itself, many occasions are not suitable for the selection of rubber vibration damping products. Rubber will become brittle at -30℃ and lose its own elastic deformation, so it will not play a role in vibration damping. In addition, rubber can not withstand high temperatures, as long as more than 75 ℃, its internal structure has changed, its elasticity will completely disappear, of course, no longer have any vibration damping function. If the temperature continues to rise, there is a possibility that it will burn up. Select the appropriate shock absorber according to local conditions.
