Rubber waterstop bands and waterstop rubbers are primarily made from natural rubber and various synthetic rubbers, mixed with various additives and fillers, and then plasticized, mixed, and molded. They come in a variety of types and specifications, including bridge, mountain, P, U, Z, Y, T, H, E, and Q shapes. They are produced using natural rubber or various synthetic rubbers as the main material, mixed with a variety of additives and fillers, and processed through plasticizing, mixing, calendering, and vulcanization. They can be categorized as buried rubber waterstop bands and back-adhesive rubber waterstop bands based on usage. These waterstop materials offer excellent elasticity, wear resistance, aging resistance, and tear resistance, with strong adaptability to deformation and good waterproofing properties. Their temperature range of use is -45℃ to +60℃. Rubber waterstop bands should not be used when the temperature exceeds 70℃ or when they are subjected to strong oxidation or erosion by oils or other organic solvents. They are commonly used during the construction of underground exterior walls and backfill strips.
