Dumbbell with center bulb rubber waterstop

Rubber swellable wat Rubber water stop Rubber Waterstop is manufactured from natural rubber and synthetic rubbers with many additives and fillers by the processes of plastication, mixing and compression molding. It can be used in various concrete joints to prevent water leakage and permeation. It has excellent elasticity and it is highly resistant to abrasion, corrosion, aging and tearing. It can adapt to deformation very well and it is resistant to water. It is suitable for the temperature range of -45 °C to +60 °C. Rubber waterstop cannot be used when the temperature exceeds +70 °C and in the conditions where rubber waterstop is oxidized or corroded seriously by organic solvents.    Advantages
• Time and cost saving in jointing straight length and intersection
• High elasticity accommodates pronounced cyclic movement
• High elongation to cater for subsidence and seismic movement
• Withstands high water pressures
