Solutions To Water Containment Needs - Bentonite Waterstops
Bentonite waterstop is a kind of hydrophilic water sealing product coming with incomparable durability and higher water absorption no less than 300%. Unlike traditional clay based waterstops, this one utilizes rubber as base material to form a controlled, moisture active sealant - that means the bentonite waterstop will not expand to point losing much of integrity even being washed away by water during continually expansion.

Material
Hydrophilic Swellable Rubber Waterstop Strip Swelling Water Stop Waterbar in Construction Joint Expansion Waterstop Strip
The product is a composite made through processes like internal mixing, compounding, and extrusion.
    *Core Swelling Material: Modified sodium or calcium-based bentonite. Its layered crystal structure expands upon water absorption, which is the key to the water-stopping function.

    *Elastomer Matrix: Nitrile rubber, natural rubber, butyl rubber, etc., are commonly used to provide flexibility, elasticity, and mechanical strength.

    *Functional Additives: Include water-absorbent resins (e.g., sodium polyacrylate) to enhance expansion ratio, tackifying resins to ensure self-adhesion, and plasticizers, anti-aging agents, etc., collectively optimizing durability and application performance.
