PVC Aquaculture Membrane
PVC geomembrane: flexible impermeable sheet for containment barriers — fish ponds, aquaculture, landfills, tailings ponds, drinking water tanks, biogas digesters, agricultural canals. Thickness 0.5–1.5 mm; 0.5–0.75 mm for ponds/agriculture, 0.75–1.5 mm reinforced for landfills and potable water. Weldability is critical for leak-free installations.
Technical Specifications
| Application | Thickness | Standard | Key property |
|---|---|---|---|
| Pond / agricultural liner | 0.5 mm (20 mil) | ASTM D7176 | pH 2–12 resistant, UV-stabilized |
| Landfill liner / cover | 0.75 mm (30 mil) | ASTM D7176 / GRI-GM17 | Chemically resistant, weldable |
| Potable water tank (reinforced) | 1.0–1.5 mm | GRI-GM17 + NSF/ANSI 61 | Drinking-water certified |
| Biogas digester | 0.75–1.5 mm reinforced | Custom | Gas-tight, biogas-resistant |
Market Compliance & Import Considerations
| Region | Key standard |
| Europe | REACH phthalates/lead; NSF/ANSI 61 if drinking-water contact; HS 5903.10.90 ≈ 8% |
| USA | ASTM D7176 (PVC geomembrane); GRI GM15/GM34 (PVC-EIA); NSF/ANSI 61; HS 5903.10.15 = DUTY FREE |
Typical Applications
- Aquaculture & fish pond liners
- Drinking water tanks & reservoirs
- Landfill covers & leachate containment
- Mining tailings ponds
- Biogas digester covers
- Agricultural irrigation canals
How to Select the Right Specification
| Small backyard pond | 0.5 mm (20 mil) — ASTM D7176, UV-stabilized |
|---|---|
| Large aquaculture reservoir | 0.5–0.75 mm, thicker for continuous UV exposure |
| Municipal / hazardous landfill | Reinforced 0.75–1.5 mm / GRI-GM17, leak-detection compatible |
| Drinking water storage | Reinforced 1.0–1.5 mm / NSF/ANSI 61 certified |
| Strong solvents / hydrocarbons | Switch to PVC-KEE / PVC-EIA or HDPE — consult engineer before quoting |
Welding & Installation
| NOTE | PVC geomembrane MUST use hot-air / heat-wedge / RF / solvent welding. NOT extrusion welding. Weld overlap: 100–150 mm. |

Procurement Checklist
- Specify: tensile + tear + peel requirements, fire rating per local code, surface finish (PVDF/acrylic/matte), print ink compatibility
- All values are industry-typical ranges — we provide third-party lab test reports with every batch
- Import tariffs & anti-dumping change frequently — verify the latest WTO schedule before pricing
- Contact [email protected] with your spec requirements and target market for a quick quotation
Quality Assurance and Customization
Every PVC Aquaculture Membrane is produced under ISO 9001-controlled processes and tested to ASTM D751 for tensile, tear, and adhesion performance. Typical properties include a basis weight around 500-1500 g/m² g/m² and a Polyester scrim with PVC coating construction selected for stable welding and long service life. KeZHiBo offers custom widths, colors, and surface treatments—anti-fungal, anti-static, or FR-rated—with third-party inspection available on request, supporting both OEM volumes and project-specific specifications from prototype to delivery.
