Engineering properties of UHMW-PE
UHMW-PE delivers a combination of exceptional wear resistance, low friction, and impact strength that can outperform traditional metals and engineering plastics in selected industrial environments.
Design consideration
Its thermal expansion and tendency to deform under heat require controlled cutting parameters and careful dimensional planning.
| Property | Typical value |
|---|---|
| Molecular Weight | 3 to 9 Million g/mol |
| Coefficient of Friction | 0.10–0.22, dry vs. steel |
| Notched Impact Strength | No Break, ASTM D256 |
| Water Absorption | < 0.01% |
| Continuous Service Temperature | -260°C to +80°C |
| Machining Tolerance | ±0.05 mm–0.10 mm |
Machining capabilities
Process control for stable, accurate plastic parts
Our optimized CNC milling and turning parameters help preserve dimensional stability and surface integrity while accommodating the material’s thermal behavior.
CNC milling
3-axis and 5-axis machining for complex contours, pockets, mounting features, and custom geometries.
CNC turning
Consistent diameters for rollers, bushings, shafts, and other rotational components.
Surface finishing
Controlled feed rates produce smooth finishes that support low-friction sliding applications.
Tight tolerance control
Dimensional checks help parts fit existing assemblies without binding or premature wear.
Built for demanding environments
Industrial applications
We support engineering and procurement teams with durable UHMW-PE components designed for heavy-duty service and reduced maintenance.
Conveyor systems
Wear strips, chain guides, and curve tracks for reliable material movement.
Food processing
Moisture-resistant parts for applications requiring resistance to chemical cleaning agents.
Material handling
Impact pads, star wheels, and transition plates for demanding transfer points.
Industrial machinery
Self-lubricating bearings, bushings, and guide rails requiring minimal maintenance.

Have questions about material selection, tolerances, or design constraints? Our engineering team can help assess your application.
How does UHMW-PE reduce maintenance? +
Its low coefficient of friction, self-lubricating behavior, and high wear resistance can reduce binding, lubrication needs, and replacement frequency in sliding applications.
Which files should I provide for a quote? +
STEP, IGES, or PDF drawings are suitable starting points. Include material requirements, quantities, tolerances, and any inspection or compliance needs.
Can you support both prototypes and production? +
Yes. Our production planning supports single-piece prototypes as well as high-volume orders of 10,000 or more parts.
