MACRO SORB® Expanding Rubber Polymer Technical Profile
This advanced functional material (CAS 9003-04-7) combines elastic sealing properties with hydrophilic expansion capabilities, delivering dual water-stop effects for critical infrastructure including subways, tunnels, culverts, underwater constructions, and urban water supply systems.
Composed of a rubber matrix and hydrophilic components, the polymer absorbs water to expand multiple times its original volume, filling irregular surfaces and gaps under pressure to ensure effective sealing.

FAQ
Q1: Operational mechanism?
Expands upon moisture/heat exposure to fill gaps/cracks, forming flexible watertight seals after curing.
Q2: Expansion/curing duration?
Initial expansion: 10–30 minutes; Full curing: 24–48 hours (environment-dependent).
Q3: Environmental resistance?
Withstands water immersion, UV exposure, temperature fluctuations, and chemical corrosion.
Q4: Soundproofing capability?
Effective for vibration damping and acoustic insulation through gap-filling properties.
