Product Description
Building Base High Damping Rubber Bearings

1.HDR has a good load support ability, restoring force and damping force (energy dispersion). 
  As a result, HDR can be used as a Seismic Isolator. 

2.From the displacement cycle restoring characteristics (load versus displacement loop) for 
  HDR,it shows that HDR can maximize the Trigger Effect against the wind load and the
  Intensity Resistance effect for earthquake forces. 

3.No other devices for the Seismic Isolator are needed. 
  Therefore, it is easy to construct and maintain. It is also cost-effective. 

4.There will be almost no residual displacement even after big earthquakes. 
  Furthermore, there will be no significant change of characteristics, so replacement is not
  necessary. 

5.Changes in HDR's stiffness and damping performance due to temperature are minor
  allowing it to be used in various climates. 

6.HDR is newly developed rubber material, so its creep characteristic is superior to natural
  rubber

7.The HDR is covered with a layer of EPDM rubber. This EPDM rubber protects the internal  
  rubber from ozone and ultraviolet attack. It is designed for high durability.
