Building isolation rubber bearings can be divided into natural rubber bearings (LNR), lead rubber bearings (LRB) and high damping rubber bearings (HDR).
Natural rubber bearing (LNR) is made of natural rubber as the main raw material.
Lead rubber bearing (LRB) is a kind of lead rubber bearing. In order to improve the damping ratio and early stiffness of the isolation bearing, the wind response and microseismic are controlled.
High damping rubber bearing (HDR) is to add carbon or other elements to rubber base material, so that laminated rubber has good damping performance.
