PVC Waterstop WW250 for Construction Industry
Exhibits 300%+ elongation at break and excellent ductility, accommodating structural settlement
2.1 Core Features (Focus on Shelf Appeal)
(1) Premium Material & Superior Performance
- Mechanical Strength: Adopting reclaim-free PVC composite, it meets GB/T 18173.2-2014 and DIN 18541 standards with verified data: tensile strength ≥14MPa (exceeding the 12MPa industry minimum) , elongation at break ≥300% , and tear strength ≥25kN/m —resisting tearing during concrete pouring and structural vibration. The double-wave structure enhances shear resistance by 35% compared to single-wave models, adapting to complex joint movements.
- Environmental Adaptability: Brittle temperature ≤-30℃ (no cracking in low-temperature bending tests) and high-temperature resistance up to 65℃ (no softening or deformation). Water absorption rate ≤0.3% , stable in long-term submerged environments; it resists weak acids (pH 3-10), alkalis, and municipal sewage —suitable for sewage treatment plants and coastal projects.
- Durable Aging Resistance: After 70℃×72h hot-air aging, tensile strength retention ≥10MPa and elongation retention ≥240% , ensuring a service life of over 30 years in underground or shaded environments—reducing long-term replacement costs.
(2) WW Structure & 250mm Width Advantage
- Double-Wave Elastic Core: The 6-segment dual-arc design forms a "double waterproof barrier," absorbing 20mm of multi-directional displacement (horizontal/vertical) . Unlike single W-type waterstops, it avoids "single-point failure"—even if one wave deforms, the other maintains sealing, making it ideal for large joints in dams, reservoirs, and tunnel segments .
- 250mm Wide Flanges: Equipped with 6-8 diamond-shaped anti-skid ribs (height ≥10mm) on both sides, increasing bonding force with concrete by 40% compared to smooth surfaces . The width covers 20-25cm joints in one piece, reducing welds by 30% vs. 200mm narrow models—lowering leakage risks from joint seams .
- Precise Dimensions: Width tolerance ±7.5mm, standard thickness 5.0±0.5mm (customizable 4-8mm) , each roll 25m long (industry standard) —fits most project batch needs. Shore A hardness of 65-75 balances rigidity for installation stability and flexibility for deformation absorption.
(3) Compliance & Easy Construction
- Quality Certifications: Passes third-party hydrostatic pressure tests (withstanding 70m water depth) and complies with FDA 21 CFR 175.300 standards for drinking water contact —safe for domestic water tanks and reservoirs.
- Simplified Installation: Can be cut with a utility knife; on-site joints are sealed via hot-melt welding (140-160℃) using a standard PVC welding gun —no professional equipment required. Pre-punched stainless steel eyelets (10cm spacing, optional) enable quick fixing to steel reinforcement, preventing displacement during pouring . Welded joints retain 95% of the parent material’s strength, ensuring integral waterproofing.
2.2 Application Scenarios (Target Buyer Needs)
Tailored for dynamic waterproofing in medium-to-large projects:
- Water Conservancy Engineering: Medium-to-large reservoirs, irrigation canals, culverts, and dam auxiliary structure joints (resistant to long-term submerged erosion) .
- Civil & Tunnel Engineering: Super high-rise basement wall/floor joints, large retaining walls, prefabricated building seams, and tunnel expansion joints (adapting to structural settlement and vibration) .
- Municipal & Environmental Protection: Underground utility tunnels, large rainwater regulation tanks, subway station main structure seams, and sewage treatment pool circumferential joints .
2.3 Shelf Advantages (For Procurement Decision-Making)
(1) Cost-Effective
- The 250mm width reduces material waste by 20% compared to 300mm wide models for matching joints; 30-year service life cuts total cost by 50% vs. replacing ordinary sealants every 5-8 years .
- Standard 25m rolls fit bulk project needs, while customizable 10m+ short rolls adapt to small maintenance tasks—avoiding inventory pressure.
(2) After-Sales Guarantee
- Quality Warranty: 5-year warranty for material defects (uneven thickness, rib detachment, reduced elasticity)—non-human damage eligible for free replacement.
- Technical Support: Free provision of electronic installation videos, welding guides, and cross-section drawings; 24-hour online consultation for on-site issues (e.g., double-wave structure positioning, low-temperature construction).
(3) Supply Reliability
- Packaged in moisture-proof polyethylene film to prevent sun/rain damage during transportation . Monthly supply capacity reaches 120,000 meters, 5-7 day delivery lead time—ensuring timely supply for project schedules.
