Super Absorbent Polymer

Expanding Rubber, also referred to as water-swelling rubber or hydrophilic expansion rubber, is an advanced functional polymer material that combines elastic sealing properties with water-absorbing expansion capabilities, delivering a dual water-stop effect. This innovative material is extensively utilized in critical infrastructure projects such as subways, culverts, tunnels, underwater constructions, and urban water supply systems. Composed of a rubber matrix and hydrophilic components, expanding rubber can absorb water and swell to several times its original volume. This unique property allows it to fill irregular surfaces, gaps, and cavities under significant pressure, ensuring effective sealing and water leakage prevention.
