DGK-POM DD4-5ML Conductive POM and Conductive Plastics. This route is relevant when ESD behavior must be combined with sliding wear performance and precision molding.
1. Background / Problem
POM is widely used in gears, rollers, bushings and sliding blocks because it has low friction, good dimensional stability and a naturally smooth surface. In electronics handling or precision equipment, the same part may also need controlled ESD behavior.
A material that is only wear-resistant may remain insulating. A material that is only conductive may lose the low-friction and surface-quality advantages that made POM attractive in the first place.
2. Technical Difficulty / Why It Happens
Conductive modification can change POM friction behavior, toughness, gloss and molding shrinkage. If the conductive network is not stable, resistance may vary after sliding wear or after polishing of the contact surface.
For rollers and precision components, the validation should include resistance, surface finish, dimensional tolerance, wear track condition and noise or vibration behavior.
3. DEYU Material Direction
DEYU may recommend DGK-POM DD4-5ML as the conductive POM direction. Existing product data positions this grade at 10^4-10^5 ohm, with glossy surface and good toughness, for ESD wear-resistant structural parts and electronic accessories.
4. Reference Product Data
| Property | DGK-POM DD4-5ML Direction |
|---|---|
| Base resin | POM |
| Conductive direction | 10^4-10^5 ohm |
| Surface / toughness | Glossy surface and good toughness |
| Processing | Injection molding |
| Typical applications | ESD wear-resistant structural parts, rollers, sliding blocks and electronic accessories |
5. Customer Debugging / Validation Scenario
A customer used standard POM rollers in a precision transport module. Wear and noise were acceptable, but static accumulation caused dust attraction and unstable electronic handling. A previous conductive trial improved resistance but increased surface roughness and early wear marks.
6. Validation Data Table
| Item | Standard POM | Previous conductive POM trial | DEYU DGK-POM DD4-5ML trial direction |
|---|---|---|---|
| Trial quantity | 600 pcs | 800 pcs | 1,200 pcs |
| Surface resistance | >10^12 ohm | 10^5-10^7 ohm | Target 10^4-10^5 ohm |
| Visible wear track after internal cycle test | Low | Medium | Target low to medium |
| Surface gloss rejection | 0.8% | 4.5% | Target <2.0% |
| Roller noise complaint | 2.5% | 5.0% | Target <3.0% |
| Dimensional rejection | 1.8% | 3.6% | Target <2.5% |
| Internal pass rate | 82% | 78% | Target >90% |
This is a validation scenario, not a published customer case.
7. Result Interpretation
For conductive POM, the question is not only whether the part becomes conductive. The part must still keep the low-friction, smooth-surface and dimensional advantages expected from POM.
The best validation sequence is plaque resistance first, then molded-part resistance, then wear and dimensional checks on the actual roller or sliding geometry.
8. Suitable Applications
- Conductive POM rollers
- ESD sliding blocks
- Precision gears and bushings
- Electronic handling accessories
- Wear-resistant structural parts requiring resistance control
9. What Buyers Should Provide
Buyers should provide the target resistance range, current POM grade, sliding speed, contact load, wear or noise data, part drawing, tolerance requirement, lubrication condition and expected production volume.
Conclusion
Final selection should be confirmed on the actual molded part: resistance, processing, mechanical behavior, appearance and service conditions need to be evaluated together.
