XPS Foam Board Machine vs Geomembrane Production Line
Two of the highest-demand product lines globally — XPS foam board for building insulation and HDPE geomembrane for waterproofing — serve massive, growing infrastructure markets. Both are produced on lines from Qingdao Precision Machine.
XPS Foam Board Machine: Thermal Insulation
Extruded Polystyrene (XPS) foam board is the premium thermal insulation material requiring high compressive strength, moisture resistance, and long-term R-value stability. Unlike EPS, XPS is extruded through a slot die with a blowing agent — creating a fully closed-cell structure.

XPS Applications
Building & Construction
- External wall insulation (ETICS)
- Flat roof insulation
- Floor insulation under screed
- Basement wall insulation
Civil Engineering
- Road subgrade insulation
- Railway embankment thermal break
- Bridge deck insulation
- Tunnel thermal insulation
XPS production: extrusion section and downstream cutting/stacking.
XPS Machine: Specifications
| Parameter | Standard | High-Output |
|---|---|---|
| Extruder | Tandem single screw | Tandem — larger primary |
| Blowing agent | CO₂ or HFC-134a | CO₂ or hydrocarbon |
| Board thickness | 20–120 mm | 20–200 mm |
| Output (kg/h) | 200–350 | 350–600 |
| Fire rating | Class B2 / B1 with FR additive | Class B1/B2 selectable |
Blowing Agent Compliance: CO₂-blown XPS meets the strictest EU regulations and is increasingly mandated in European markets. Qingdao Precision supplies both options with operator training.
Geomembrane Production Line
HDPE and LLDPE geomembrane — a smooth or textured impermeable liner — is critical for environmental protection. Applications span landfills, mining heap leach pads, water reservoirs, and aquaculture ponds.

Geomembrane Applications
Environmental Containment
- Municipal solid waste landfill liner
- Hazardous waste containment
- Mining tailings dam liner
Water Management
- Drinking water reservoir liner
- Canal and irrigation channel
- Aquaculture pond liner
Geomembrane Machine: Specifications
| Parameter | Standard | Wide-Width |
|---|---|---|
