The material in the specific joint open weight range within, even joint open change, contact surface stress is almost unchanged, is in incomplete closure of the joint will not produce segment ends had high stress, it can fully maintain contact stress.
Porous type rubber water stop belt can reduce the compressive force, increase of segment joint open, it is not easy to long compression stress relaxation and permanent deformation. And the expansion rubber composite sealing pad is based on the "double insurance", if the EPDM sealing pad leakage, corrosion expansion type expansion rubber strip in case of water will begin to slow the expansion, with water shut-off of water to second waterproof effect.
Product features:
good elasticity, aging resistance, chemical resistance, ozone resistance. In a wide temperature range, can play excellent sealing performance, excellent weatherability. Suitable for cold area construction.
Application:
the product is suitable for the construction of the underground engineering pipeline joints waterproof seal. Mainly used in infrastructure projects, underground facilities, tunnels, tunnels, water conservancy, subway and other projects
