Flexible Rubber Water-stop strips

Mainly used for infrastructure projects, underground facilities, tunnels, water conservancy, metro project. Product Performance and Characteristic

Rubber Water-stop Strip is use of domestic high quality natural rubber and various kinds of synthetic rubber as the main raw material, adding various accelerator agent and filling agent, through the process of refining, mixing, vulcanization, and mould pressing. This product is use of the high elasticity and compression deformation of rubber. It can produce elastic deformation in all kinds of load, and can fastening the seal. And it plays an effectively role of prevent the construction component of water leakage, seepage, and shock absorption, so as to ensure that the service life of the engineering construction.

                                                 

Product UsageMainly used for infrastructure projects, underground facilities, tunnels, water conservancy, metro project. For the gate, dam construction, engineering, underground structures with adjustable concrete pouring.
