Hirun Sliding Material 

HSM (Hirun Sliding Material) is a new type of polymer developed by Hirun for bridge bearing and anti-seismic devices with the characteristics of high pressure strength, stable friction performance, excellent wear resistance, and high temperature resistance etc. As the core part of Hirun friction pendulum bearings, HSM can meet the relevant test requirements of the European standard EN15129 and EN1337. The products have been widely applied to bridges and seismic isolation building projects domestically and abroad.
