SBS waterproof coil is mainly used in building walls, roofs, tunnels, highways, landfills, etc., to resist external rain and groundwater leakage, a flexible building material product that can be rolled into a roll, as a non-leakage connection between the engineering foundation and the building, is the waterproof road barrier of the entire project. It plays a vital role in the whole project, and the waterproof coil requires good water resistance. Sinosteel National inspection engineers introduced in detail the waterproof coil test indicators thickness, mass per unit area, tensile property, impermeability, low temperature flexibility, low temperature bending, heat resistance, thermal aging, etc., the customer according to the use of the environment to determine the specific index requirements as the basis for testing.
