🧩 POM+CF10 – Polyacetal (Delrin) with 10% Carbon Fiber
(A technical Polyoxymethylene (POM) reinforced with 10% carbon fiber, designed for applications requiring high rigidity, low weight, electrical conductivity, and excellent wear resistance. Perfect for precision mechanisms and sliding technical parts.)
🔹 What is POM+CF10
POM+CF10 is a high-performance composite where the 10% carbon fiber (CF) reinforcement increases mechanical rigidity by 25–30%. It features superior thermal resistance, partial electrical conductivity, and a reduced friction coefficient. It is excellent for technical parts exposed to friction and moderate mechanical loads without becoming brittle.
🔧 Composition
| Component | Typical Ratio | Role |
| Polyacetal (POM) | ≈ 90 % | Self-lubricating and wear-resistant matrix |
| Carbon Fiber (CF) | ≈ 10 % | Increases rigidity, conductivity, and stability |
| Additives | < 2 % | Oxidation protection and thermal stability |
🚗 Where POM+CF10 is used in the automotive industry
| Component | Example parts | Observations |
| Gears / Actuators | Bosch, Continental | Low friction, high precision |
| Sliders / Bearings | VW, Renault | High durability, maintenance-free |
| ABS / EGR Components | Toyota, Ford | Moderate conductivity, thermal stability |
| Lightweight Fittings | Dacia, Opel | Low weight, good mechanical resistance |
🔧 Welding Temperature and Methods
| Method | Optimal Temp | Observations |
| Hot Air | 250 – 270 °C | Easy to weld, uniform melting, no bubbles |
| Heat Plate (Mirror) | 250 – 265 °C | Ideal – Smooth surface with high strength |
| Plastic Extrusion | 260 °C | Recommended – use POM or POM+CF rod |
🔩 Material Compatibility
- ✅ Compatible: POM, POM-C, POM-H.
- ⚠️ Partially Compatible: POM+CF, POM+PTFE (requires preheating).
- ❌ Incompatible: PA, PP, PE, ABS (chemically and thermally incompatible).
💡 ReplastMD Recommendation: Weld at ~260 °C using POM+CF or pure POM rods. Carbon fibers offer great warping resistance; avoid localized overheating to prevent fiber degradation.
🧠 How to Identify POM+CF10
- Engraved marking: > POM+CF10 <, > DELRIN CF <, > HOSTAFORM CF10 <.
- Texture: Very smooth, slightly glossy, satin-black appearance.
- ReplastMD practical test: Very clean, shiny edges when cut; fine fibers are visible. Flame: burns rapidly with a sharp formaldehyde scent.
