High damping isolation rubber bearings, also known as HDR bearings, are products designed according to the national standard GB20688 for domestic high resistance isolation rubber bearings. They are made by adding various additives to natural rubber to improve its damping performance (increase hysteresis loss and reduce storage modulus), and then using this damping rubber to make a laminated product of steel plate and rubber that is similar to the structure of ordinary rubber bearings through thermal vulcanization.
