Expansion joints are widely used in the flooring, roofing, and ground surfaces of large public buildings; depending on the design, they are categorized into expansion joints, settlement joints, and seismic joints. For single-layer expansion joint structures, high-performance sealing materials such as platinum-cured silicone, EPDM, chloroprene, or TPV can be selected
For double-layer structures—characterized by extra-large sealing strips and complex multi-cavity designs—TPV is the recommended material; it better accommodates structural displacement, provides long-lasting sealing and structural protection, and ensures the overall safety and durability of the building
The performance and service life of expansion joints are directly linked to the building's structural design, the installation of the sealing strips, and the material properties of the strips themselves
