Request Quotation HDPE Liner 2mm GM13: Engineering Guide
What is Request Quotation HDPE Liner 2mm GM13?
Request quotation HDPE liner 2mm GM13 refers to the formal procurement inquiry for 2.0 mm thick high-density polyethylene geomembrane that meets GRI GM13 (Geosynthetic Research Institute) standard — the most stringent specification for landfill liners, mining heap leach pads, and hazardous waste containment. For procurement managers, EPC contractors, and mining engineers, understanding how to request quotation HDPE liner 2mm GM13 is critical because 2.0 mm thickness provides 40–50% higher puncture resistance than 1.5 mm (450–520 N vs. 320–380 N), higher tear resistance, and greater safety margin for high-head applications (> 10 m) or aggressive leachate. GRI GM13 requires virgin PE100/PE4710 resin, PENT ≥ 500 hours, OIT ≥ 100 minutes, HP-OIT ≥ 400 minutes, carbon black 2–3%, and full mechanical properties (tensile, tear, puncture). This guide provides engineering data to request quotation HDPE liner 2mm GM13: specifications to include, test report requirements, volume pricing (€14–22/m² FOB), and procurement checklist for landfill, mining, and industrial projects.

Material Structure and Composition of HDPE Liner 2mm GM13
Understanding material composition helps in request quotation HDPE liner 2mm GM13.
| Component | Material | Function | Quality Indicator for Quotation |
|---|---|---|---|
| Base Resin | PE100 or PE4710 bimodal (hexene/octene co-monomer) | Provides mechanical strength, stress crack resistance | Require resin supplier certificate (e.g., Borealis, LyondellBasell).}, |
| Carbon Black | 2.0–3.0% furnace black | UV protection, antioxidant | Request ASTM D1603 test report.}, |
| Antioxidants | Primary (hindered phenol) + secondary (phosphite) | Prevents thermal/oxidative degradation | OIT ≥ 100 min (standard), HP-OIT ≥ 400 min.}, |
Engineering insight: When you request quotation HDPE liner 2mm GM13, verify resin source. PE100/PE4710 bimodal resin with hexene co-monomer is required for PENT ≥ 500 hours.
Manufacturing Process: How Quality Affects Request Quotation HDPE Liner 2mm GM13
Understanding production helps buyers evaluate suppliers during request quotation HDPE liner 2mm GM13.
Resin compounding: Virgin PE100 resin + carbon black + antioxidants blended. Premium manufacturers use closed-loop automated batching.
Extrusion: Flat die extrusion (200–220°C). Online thickness monitoring (±5% tolerance). 2.0 mm target → 1.9–2.1 mm acceptable.
Calendering / polishing: Smooth or textured surface as specified. 2.0 mm smooth liner for most applications.
Cooling: Controlled cooling to prevent residual stress.
Quality inspection: Full GRI GM13 testing: tensile, tear, puncture, PENT, OIT, HP-OIT, carbon black. Request test reports with your quotation.
Roll winding: Consistent roll dimensions for shipping. 2.0 mm × 7 m × 100 m roll weighs approx. 1,400–1,500 kg.
Performance Comparison: 2.0 mm HDPE vs. Alternative Thicknesses for GM13
Comparing 2.0 mm HDPE liner with 1.5 mm and 2.5 mm for request quotation HDPE liner 2mm GM13 context.
| Thickness | Puncture Resistance (N) | Tear Resistance (N) | Hydraulic Head Capacity | Relative Cost | Typical Applications | |
|---|---|---|---|---|---|---|
| 1.5 mm | 320 – 380 | 125 – 150 | ≤ 15 m | 1.0x (baseline) | Standard landfill, mining, ponds | |
| 2.0 mm | 450 – 520 | 170 – 200 | ≤ 25 m | 1.3 – 1.4x | High head (> 10 m), aggressive leachate, hazardous waste | |
| 2.5 mm | 550 – 650 | 220 – 260 | ≤ 35 m | 1.7 – 1.8x | Extreme head, very sharp subgrade, nuclear waste |
Conclusion: Request quotation HDPE liner 2mm GM13 for applications requiring higher puncture resistance and head capacity than 1.5 mm, at 30–40% cost premium.
Industrial Applications for Request Quotation HDPE Liner 2mm GM13
Typical projects requiring 2.0 mm HDPE liner.
Hazardous waste landfills (Subtitle C): 2.0 mm primary liner over clay or GCL. Regulatory requirement for hazardous waste.
Mining heap leach pads (copper, gold, uranium): High head (> 10 m) and sharp ore. 2.0 mm provides puncture safety margin.
Tailings storage facilities (TSF) with high head: Primary liner for tailings dams with head > 15 m.
Industrial chemical ponds (acid, caustic, solvents): Aggressive chemicals require thicker liner for longer service life.
Large reservoirs (potable water, high head): Head > 15 m requires 2.0 mm for safety factor.
Common Industry Problems When Request Quotation HDPE Liner 2mm GM13
Real-world issues to avoid during request quotation HDPE liner 2mm GM13 process.
Problem 1: Supplier offers "equivalent" but not GM13 certified
Root cause: Non-certified liner may have lower PENT (< 500 h) or OIT (< 100 min). Solution: In your request quotation HDPE liner 2mm GM13, require GRI GM13 test report from accredited lab (TÜV, SGS). Reject self-declared "equivalent."
Problem 2: Thickness tolerance exceeds ±10% — thin spots reduce puncture resistance
Root cause: Poor extrusion control. Solution: Request thickness profile data. Reject if any measurement < 1.8 mm.
Problem 3: Inconsistent OIT across rolls (variation > 20%)
Root cause: Poor antioxidant dispersion or varied resin lots. Solution: Request OIT test for every 10 rolls. Same resin lot for entire order.
Problem 4: Long lead time (12+ weeks) for 2.0 mm liner
Root cause: Supplier lacks production capacity or doesn't stock 2.0 mm. Solution: When you request quotation HDPE liner 2mm GM13, ask for lead time and stocking policy.
Risk Factors and Prevention Strategies for Request Quotation HDPE Liner 2mm GM13
Risk: Supplier substitutes recycled content to lower price: Fails PENT and OIT. Mitigation: Require virgin resin certificate from HDPE manufacturer. Test PENT independently.
Risk: No independent third-party testing: Supplier's QC may be biased. Mitigation: Include third-party testing (SGS, Intertek, TÜV) in your request quotation HDPE liner 2mm GM13.
Risk: Shipping damage to heavy rolls (2.0 mm × 7 m × 100 m ≈ 1,500 kg): Roll deformation, edge damage. Mitigation: Specify packaging: steel core, edge protectors, steel strapping, UV wrap.
Risk: Price volatility due to resin cost (HDPE resin price fluctuates): Quotation valid for limited time. Mitigation: Request price validity (30–60 days). Consider fixed-price contract for large orders.

Frequently Asked Questions: Request Quotation HDPE Liner 2mm GM13
Q1: What documents should I request when asking for a quotation?
Request: GRI GM13 test report (for 2.0 mm), resin certificate (virgin PE100/PE4710), thickness profile, roll dimension sheet, and ISO 9001 certificate. This is essential for request quotation HDPE liner 2mm GM13.
Q2: What is the typical price for 2.0 mm HDPE GM13 liner?
€14 – 22/m² FOB (Asia/Europe) depending on quantity. Volume discount: 10,000+ m²: 5–10% off; 50,000+ m²: 10–15% off. Add shipping (€2–4/m²) for CIF pricing.
Q3: What is the minimum PENT required for 2.0 mm GM13 liner?
≥ 500 hours per GRI GM13. For high-head or aggressive leachate applications, request PENT ≥ 800 hours. Specify in your request quotation HDPE liner 2mm GM13.
Q4: How long does it take to produce 50,000 m² of 2.0 mm HDPE liner?
4–8 weeks depending on supplier's production capacity. A manufacturer with 3+ extrusion lines can produce 50,000 m² in 3–4 weeks. Include lead time in request quotation HDPE liner 2mm GM13.
Q5: Can 2.0 mm GM13 liner be used for potable water?
Yes, if resin is NSF/ANSI 61 certified. Specify NSF certification in your request quotation HDPE liner 2mm GM13 for potable water projects.
Q6: What is the difference between GM13 (HDPE) and GM17 (LLDPE)?
GM13 is for HDPE with higher stiffness and stress crack resistance. GM17 is for LLDPE (more flexible). For 2.0 mm, GM13 is standard for hazardous waste and mining.
Q7: How many rolls of 2.0 mm HDPE liner fit in a 40 ft container?
2.0 mm × 7 m × 100 m rolls weigh ~1,500 kg. A 40 ft HC container holds 4–5 rolls (～20,000–25,000 m² per container). Thicker liner = fewer m² per container.
Q8: What is the acceptance criteria for thickness tolerance?
GRI GM13 allows ±10% (1.8–2.2 mm for nominal 2.0 mm). Premium manufacturers achieve ±5% (1.9–2.1 mm). Request thickness profile data in your request quotation HDPE liner 2mm GM13.
Q9: How to verify that a supplier is GRI GM13 certified?
GRI certification is per product line, not per company. Request the GRI certificate number and verify on GRI website. Require test reports from accredited lab.
Q10: What payment terms are typical for large HDPE liner orders?
30% deposit, 70% against shipping documents (Letter of Credit). For repeat suppliers, 30% deposit, 40% before shipment, 30% after delivery. Include 5–10% holdback until independent testing passes.
