Delay-Swelling Composite Rubber Strip – Controlled Expansion Seal for Complex Concrete Structures
Product Overview This delay-swelling rubber strip combines a hydrophilic core with a coated outer layer to delay expansion during the construction phase. It is ideal for areas prone to early water exposure.
Features Controlled delay before swelling begins Reduces premature expansion risk Composite structure with reliable sealing Retains elasticity after expansion.
Technical Specifications Core: Hydrophilic rubber; Coating: Polyethylene or EVA Expansion Delay: 48–72 hours Full Expansion: 200–300% Sizes: 20×10mm, 30×5mm, 25×8mm Temperature Resistance: -30°C to +70°C Compression Strength: ≥ 2.0 MPa.
Applications Rain-prone construction zones Tunnel boring machine (TBM) segments Wastewater treatment structures Lift pits and sunken basements.
Customization Options Delay time adjustable via coating Multiple shape profiles per project Pre-welded corners or T-sections Branding and QR code printing.
