All materials
LNP
Lubricomp — self-lubricating compounds
Bearings, gears and slides that run dry.
Properties
Indicative values| LNP | |
|---|---|
| Continuous service temp. | per base resin |
| Melt temperature | per base resin |
| Mould temperature | per base resin |
| Minimum wall | per base resin |
| Moisture uptake | per base resin |
| Chemical resistance | per base resin |
| Coefficient of friction | very low |
| Dielectric performance | per base resin |
| Flammability | grade dependent |
| Relative material cost | medium |
Grades
Grade choice changes the process window, tool wear and shrinkage — more often than the choice of polymer family does.
| Grade | Filler | |
|---|---|---|
| PA + PTFE | PA base, PTFE filler | The cheapest sliding solution. Limited by the base resin's service temperature. |
| POM + PTFE | POM base, PTFE filler | Dimensional stability with low friction. Guides and gears. |
| PPS / PEEK + PTFE | high-temperature base | Dry running at elevated temperature. Highest cost. |
Achievable tolerances
Nominal size bands to DIN 16742. Tolerances on critical features are agreed individually, after DFM and flow simulation.
| Nominal size | Tolerance |
|---|---|
| ≤ 25 mm | ±0,05 mm |
| 25 – 100 mm | ±0,10 mm |
| 100 – 200 mm | ±0,15 mm |
| > 200 mm | ±0,25 mm |
Applications
| Industry | Example |
|---|---|
| Textile | Continuously running components without lubrication |
| Machinery | Gears, guides, bearing bushes |
