hdpe geomembrane price

HDPE geomembrane is a high-density polyethylene impermeable liner manufactured for containment, isolation, and environmental protection applications. In engineering procurement, hdpe geomembrane price is primarily determined by resin grade, thickness, surface structure, and compliance with international standards.

Technical Parameters and Specifications

Typical technical parameters used in commercial and EPC projects are listed below:

• Density: ≥0.94 g/cm³

• Thickness range: 0.5 mm – 3.0 mm

• Tensile strength at yield: ≥15 MPa (ASTM D6693)

• Elongation at break: ≥700%

• Carbon black content: 2.0%–3.0%

• Oxidative induction time (OIT): ≥100 min (Std), ≥400 min (HP)

• Service temperature: -40°C to +60°C

These parameters directly influence long-term performance and therefore impact hdpe geomembrane price in international procurement.

Structure and Material Composition

HDPE geomembrane structure is engineered for durability and chemical resistance:

• Base polymer: Virgin HDPE resin with high molecular weight

• Carbon black: UV stabilization and oxidation resistance

• Additives: Antioxidants and thermal stabilizers

• Surface options: Smooth, single-textured, double-textured

Manufacturing Process

The manufacturing process follows controlled industrial steps:

1. Raw material batching and gravimetric feeding

2. Extrusion through flat-die or blown-film equipment

3. Online thickness and density monitoring

4. Surface texturing (if required)

5. Cooling, trimming, and roll winding

6. Quality inspection and laboratory testing

Advanced extrusion equipment and quality control systems are major contributors to hdpe geomembrane price.

Industry Comparison

Application Scenarios

HDPE geomembranes are widely specified by:

• EPC contractors for landfill liners and caps

• Mining companies for heap leach pads and tailings ponds

• Water authorities for reservoirs and canals

• Industrial developers for chemical containment

Project scale and regulatory requirements strongly affect hdpe geomembrane price.

Core Pain Points and Solutions

• Inconsistent thickness: Solved by online gauge control systems

• Premature aging: Addressed through high OIT formulations

• Weld seam failure: Mitigated with qualified welding procedures

• Cost uncertainty: Reduced via clear technical specifications and volume planning

Risk Warnings and Mitigation

Using non-compliant geomembranes may lead to leakage, regulatory penalties, and premature replacement. Buyers should verify resin origin, test reports, and production traceability to avoid hidden risks that distort hdpe geomembrane price.

Procurement and Selection Guide

1. Define application environment and chemical exposure

2. Select required thickness based on load and lifespan

3. Confirm compliance with ASTM or GRI standards

4. Request batch-specific test reports

5. Evaluate welding compatibility and field installation

6. Compare total lifecycle cost, not unit price only

Engineering Case Example

In a 2023 mining tailings project, a 2.0 mm double-textured HDPE geomembrane was installed over 120,000 m². The selection prioritized high OIT values and textured surfaces for slope stability. Optimized sourcing reduced overall hdpe geomembrane price by balancing resin grade and roll width efficiency.
