Geomembrane 200 Micron Technical Specification Guide
Geomembrane 200 Micron is a lightweight polymeric impermeable sheet (0.20 mm thickness) designed for short- to medium-term moisture barrier, agricultural lining, and basic containment applications where low mechanical stress and cost efficiency are key considerations.
Technical Parameters and Specifications
The performance of Geomembrane 200 Micron depends on resin grade (HDPE or LDPE) and production method. The following table outlines typical technical values for 0.20 mm smooth sheets used in agriculture and temporary lining systems.
| Property | Typical Value (200 Micron) | Test Standard |
|---|---|---|
| Nominal Thickness | 0.20 mm (200 µm) | ASTM D5199 |
| Thickness Tolerance | ±10% | ASTM D5199 |
| Density (HDPE grade) | ≥ 0.940 g/cm³ | ASTM D1505 |
| Tensile Strength at Yield | ≥ 8–10 MPa | ASTM D6693 (modified) |
| Elongation at Break | ≥ 400% | ASTM D6693 |
| Tear Resistance | ≥ 60 N | ASTM D1004 |
| Water Vapor Transmission | < 1.0 g/m²/day | ASTM E96 |
| UV Stabilization (optional) | Carbon black 2–2.5% | ASTM D4218 |
Due to its reduced thickness, Geomembrane 200 Micron is not suitable for heavy-load containment such as landfill base liners but performs effectively in low-stress environments.
Structure and Material Composition
Geomembrane 200 Micron is typically manufactured as a single-layer or co-extruded polymer sheet:
Base Polymer: HDPE or LDPE resin
Carbon Black: UV protection (for outdoor use)
Antioxidants: Thermal aging resistance
Processing Additives: Improve extrusion stability
Optional Additives: Anti-slip or anti-fog (agricultural use)
For cost-sensitive markets, recycled content may be used, but this affects durability and mechanical strength.
Manufacturing Process
1. Raw Material Preparation
Polymer granules are dried and mixed with stabilizers and carbon black masterbatch.
2. Film Extrusion
Blown film extrusion is commonly used for 200 micron sheets. Resin is melted at 170–220°C and inflated into a bubble to achieve thickness control.
3. Thickness Calibration
Air ring and haul-off speed regulate film thickness to maintain 200 micron specification.
4. Cooling and Winding
The sheet is collapsed, trimmed, and wound into rolls (typically 2–6 m width).
5. Quality Control Testing
Sampling includes tensile, thickness, and visual inspection before packaging.
Industry Comparison
| Material | Thickness Range | Load Capacity | Design Life | Cost Level |
|---|---|---|---|---|
| Geomembrane 200 Micron | 0.20 mm | Low | 1–5 years | Low |
| HDPE 1.0 mm | 1.0 mm | High | 15–25 years | Moderate |
| PVC Film 0.3 mm | 0.30 mm | Moderate | 5–10 years | Moderate |
| Compacted Clay | N/A | High | Variable | High installation cost |
Geomembrane 200 Micron is selected primarily for budget-controlled or temporary waterproofing solutions.
Application Scenarios
Agricultural Distributors: Pond lining, irrigation canals
Construction Contractors: Concrete curing barrier
EPC Projects: Temporary containment during civil works
Importers/Wholesalers: Bulk supply to farming sectors
Landscaping Firms: Decorative pond waterproofing
Core Pain Points and Solutions
1. Puncture Damage from Subgrade
Solution: Use sand cushioning or geotextile underlayer.
2. UV Degradation in Outdoor Exposure
Solution: Specify UV-stabilized Geomembrane 200 Micron.
3. Seam Leakage
Solution: Apply hot air welding or adhesive overlap sealing.
4. Short Service Life
Solution: Confirm resin grade and avoid recycled materials for long-term projects.
Risk Warnings and Mitigation
Not recommended for hazardous waste containment.
Avoid installation over sharp stones or debris.
Limit heavy vehicle traffic over exposed liner.
Verify roll labeling and thickness before installation.
Procurement and Selection Guide
Define project type (temporary vs permanent).
Confirm required service life.
Specify HDPE or LDPE grade.
Request laboratory test report for 200 micron thickness.
Check UV stabilization requirement.
Verify roll dimensions and packaging method.
Assess supplier production capacity.
Include field inspection plan in contract.
Engineering Case Example
Project: Agricultural irrigation pond – 6,000 m²
Material: UV-stabilized Geomembrane 200 Micron
Installation System: Compacted soil + 50 mm sand cushion + 200 micron liner + anchor trench perimeter
Outcome: Achieved cost-effective water retention for seasonal irrigation cycle with no leakage observed during first 24 months.
