HDPE Sheet — Linings & containment

Description

1. Product Overview

This product is a high-density polyethylene (HDPE) geomembrane sheet, manufactured via flat-die extrusion for uniform thickness and stress resistance. It is primarily used as a lining system for containment structures such as landfills, mining leach pads, and industrial tanks. The key value proposition is its impermeability and resistance to a wide range of chemicals and UV exposure, ensuring environmental protection and asset integrity. Strategically, it is indispensable for projects requiring ISO 9001 and GRI-GM13 compliance, mitigating liability and reducing long-term maintenance CAPEX.

2. Key Specifications & Technical Characteristics

• Chemical composition: Virgin HDPE resin with 2–3% carbon black, no recycled content

• Grade: ASTM GRI-GM13, PE4710 equivalent

• Physical characteristics: Black, textured or smooth finish; thickness range: 0.5 mm to 3.0 mm; density: ≥0.94 g/cm³; tensile yield strength: ≥15 kN/m (per ASTM D6693)

• Packaging options: Industrial rolls shrink-wrapped on steel pallets; roll width: 5–8 m; roll length: 50–200 m

• Shelf life: 5 years in original packaging below 50°C; UV stability >3,000 hours accelerated weathering

3. Core Industrial Applications

• Primary industries: Mining, waste management, water treatment, petrochemical, civil engineering

• Specific use cases: Heap leach pads, landfill bottom liners, secondary containment berms, potable water reservoirs, industrial evaporation ponds

• Performance advantage: Higher weld strength (≥80% of parent material) and lower permeability (≤1×10⁻¹² cm/s) compared to PVC, LLDPE, or clay liners

• Efficiency: Lighter than reinforced concrete and clay; installs 60% faster with automated wedge welding, reducing labor costs

4. Competitive Advantages

• Quality consistency: 100% inline thickness scanning & pinhole detection per roll; lot traceability to resin batch

• Supply reliability: Multi-plant production (Asia, Middle East, Europe) with 48-hour emergency replenishment option

• Logistics capability: Direct container loading or break-bulk for project sites; on-site technical supervision available for large orders

• Price competitiveness: Tier-1 virgin resin pricing with 6–8% lower landed cost than European or North American equivalents

• Sustainability: 100% recyclable post-use; carbon-neutral production facility option

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): 20 MT per product grade/specification

• Bulk loading capacity: 22–26 MT per 20’ standard container (depending on roll diameter and sheet thickness)
