Shield segment elastic rubber gasket is currently the mainstream material used in Western European countries for sealing and water-stopping of assembled tunnel segments. It is composed of single porous EPDM rubber or porous EPDM rubber and expanded rubber to make. The material is within a specific range of seam opening. Even if the seam opening is changed, the contact surface stress is almost unchanged.

Product introduction
Shield segment elastic rubber gasket is currently the mainstream material used in Western European countries for sealing and water-stopping of assembled tunnel segments. It is composed of single porous EPDM rubber or porous EPDM rubber and expanded rubber to make. The material is within a specific range of seam opening. Even if the seam opening is changed, the contact surface stress is almost unchanged. Even when the seam is completely closed, there will not be excessive stress at the end of the segment, and it can fully maintain contact. surface stress. The porous rubber waterstop can reduce the compressive stress, increase the opening of the joints of the segment, and is not easy to cause stress relaxation and permanent deformation due to long-term compression. The composite gasket with expanded rubber is added on this basis“Double insurance, if the EPDM gasket leaks, the slow-expansion expansion rubber strip will start to expand slowly when it encounters water, stop the water with water, and play a secondary waterproof role.
The types currently produced by our company are mainly divided into three categories: EPDM rubber, slow-swelling water-swellable rubber and composite materials of the two.

EPDM rubber is a copolymer of ethylene, propylene and a small amount of non-conjugated diene. It only contains unsaturated double bonds in the side chain, so it has excellent aging resistance such as ozone resistance, heat resistance and weather resistance. , automotive seals and other fields.
