FEP， The scientific name is fluorinated ethylene propylene copolymer, which is a modified copolymer of polytetrafluoroethylene (PTFE). It perfectly inherits the excellent chemical inertness and non adhesiveness of PTFE, while crucially introducing the characteristic of melt processability. It is often regarded as an economical alternative to PFA due to its high transparency and excellent cost-effectiveness, playing a key role in demanding but cost controlled applications.
| Feature | Description | Advantages |
|---|---|---|
| Excellent Chemical Resistance | Resistant to almost all strong acids, strong bases, and organic solvents (except for molten alkali metals and fluorides). | Can be used in most corrosive chemical environments to protect equipment from corrosion. |
| Excellent Temperature Resistance | Continuous operating temperature: -200 ° C to+205 ° C. | Suitable for most high-temperature environments, it can be pasteurized and steam disinfected. |
| Excellent Non Stick & Low Friction Coefficient | Surface energy is extremely low, substances are not easily attached, and the friction coefficient is low. | Easy to clean, prevents material blockage, and ensures smooth flow. |
| Excellent Optical Performance | High transparency (visible light transmittance>95%), easy to observe. | Very suitable for pipelines, containers, and windows that require visual monitoring. |
| Melt Processability | Thermoplastic processing methods such as injection molding, extrusion, and blow molding can be used. | Capable of manufacturing complex shapes and achieving seamless welding with no risk of leakage. |
| Excellent Insulation Performance | The dielectric constant is stable and the loss factor is extremely low, especially at high frequencies. | It is an ideal insulation material for high-speed data cables and coaxial cables. |
| Flame Retardancy | Non combustible, compliant with UL94 V-0 flame retardant rating. | Improved the safety of applications in electronic and electrical fields. |
