🧩 PEEK+CF20+PTFE – Polyether Ether Ketone with 20% Carbon Fiber + Teflon
(An advanced composite based on PEEK, reinforced with 20% Carbon Fiber (CF) and modified with PTFE (Teflon) to reduce friction and increase wear resistance. One of the highest-performing thermoplastics, used in precision mechanical parts and extreme environments.)
🔹 What is PEEK+CF20+PTFE
PEEK+CF20+PTFE is a high-tech hybrid. At ReplastMD, we treat it as the ultimate solution for metal replacement. PEEK provides the thermal matrix, Carbon Fiber adds exceptional rigidity and dimensional stability, and PTFE provides internal lubrication. It withstands continuous temperatures up to 250 °C and remains stable in oily, abrasive, or chemically aggressive environments.
🔧 Composition & Properties
- Polymer Base: Polyether ether ketone (PEEK) ~70%.
- Reinforcement: Carbon Fiber (CF) ~20%.
- Lubricant: PTFE (Teflon) ~10%.
- Density: ~ 1.45 – 1.55 g/cm³.
- Melting Point: ~343 °C.
- Visuals: Carbon black with a matte metallic tint; extremely rigid.
🚗 Where it is used in the automotive industry
| Component | Example parts | Observations |
| Dry Bearings / Guides | VW, Toyota, Renault | Extremely low friction coefficient |
| EGR Valves / Pistons | BMW, Ford | Resists up to 250 °C and corrosive fluids |
| Turbocharger Zone | Mercedes, Peugeot | Dimensional stability under thermal load |
| Precision Electronics | Hyundai, Dacia | Superior thermal and mechanical insulation |
🔧 Welding and Bonding Methods
| Method | Optimal Temp | Observations |
| Hot Air | 370 – 390 °C | Only with precise digital thermal control |
| Heat Plate (Mirror) | ✅ Recommended | Clean, homogeneous, pore-free weld |
| Extrusion | ✅ Possible | Suitable for high-end technical rods/plates |
💡 ReplastMD Recommendation: Weld at ~380 °C using controlled air or teflon-coated heating plates. PEEK+CF20+PTFE is the ideal material for bearings, valves, and structural components where extreme wear resistance and low friction are mandatory.
