MACRO SORB ® Expanding Rubber Polymer High Expansion Capacity Pressure Resistance

Introduction of MACRO SORB® Expanding Rubber 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.

As superabsorbent polymers (SAPs) are a key raw material in expanding rubber, MACRO SORB® Superabsorbent Polymer has emerged as the preferred choice due to its superior water absorption and retention capabilities. Additionally, MACRO SORB® Polymer is non-toxic, eco-friendly, and safe for use, making it an ideal component for expanding rubber applications. Its exceptional performance and environmental benefits further enhance the reliability and sustainability of water-stop solutions in demanding engineering projects.

FAQ

1. How does the expanding rubber polymer work?

The polymer expands when it comes into contact with moisture or heat, filling gaps, cracks, and voids. Once cured, it forms a durable, flexible, and watertight seal.

2. How long does it take for the polymer to expand and cure?

The expansion process begins immediately upon exposure to moisture or heat, with full expansion typically occurring within 10-30 minutes. Curing time depends on environmental conditions but usually takes 24-48 hours to fully harden.

3. Is the expanding rubber polymer resistant to environmental factors?

Yes, the polymer is highly resistant to water, UV radiation, temperature fluctuations, and chemicals, making it suitable for both indoor and outdoor applications.

4. Can the polymer be used for soundproofing?

Yes, the expanding rubber polymer is effective for soundproofing applications due to its ability to fill gaps and dampen vibrations.
