High Expansion Capacity Water Swelling Rubber Pressure Resistance Swellable Waterstop

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.

• Dual Functionality: Combines elastic sealing with water-absorbing expansion for effective water-stop solutions.
• High Expansion Capacity: Swells to several times its original volume, filling gaps and irregular surfaces.
• Versatile Applications: Ideal for subways, tunnels, culverts, underwater projects, and water supply systems.
• Pressure Resistance: Seals effectively under high pressure, ensuring long-lasting performance.
• Eco-Friendly: Non-toxic and environmentally safe, especially with MACRO SORB® Superabsorbent Polymer.
• Superior Water Absorption: Enhanced by high-performance SAPs like MACRO SORB®, offering better water retention.
• Durable and Reliable: Provides robust sealing in demanding environments.
• Cost-Effective: Reduces maintenance and repair costs by preventing water leakage.
