FEP Product Overview
FEP products are high-end industrial components made from fluorinated ethylene propylene (FEP), a copolymer of tetrafluoroethylene and hexafluoropropylene. Combining the chemical inertness of PTFE with the processability of thermoplastics, they serve as strategic materials for extreme operating conditions. Core properties and applications include:
1. Extreme Performance
- Temperature Resistance:
Long-term service: -200°C to 200°C; short-term tolerance up to 260°C (e.g., engine seals). - Chemical Inertness:
Resists aqua regia, hydrofluoric acid, organic solvents (except concentrated sulfuric acid); stable under high-pressure steam. - Functional Properties:
Friction coefficient 0.04–0.34 (self-lubricating); dielectric strength 10–22 kV/mm (high-frequency insulation); UL94 V-0 flame retardancy (self-extinguishing, non-toxic).
2. Application Scenarios
- Electronics & Electrical:
High-temperature wires, 5G communication cables, semiconductor wafer carriers (zero ion leaching). - Chemical Corrosion Protection:
Reactor linings, ultrapure fluid pipelines (resists strong acids). - Medical & Health:
Catheters, blood bags (biocompatible, reusable after 134°C high-pressure sterilization). - New Energy:
Photovoltaic backsheet films, fuel cell bipolar plates (resists electrolyte corrosion).
3. Processing Methods
Formed via injection molding (290–400°C), extrusion, or blow molding. Products include:
- Tubing, films, insulation layers, and precision molded parts (e.g., bearings, gears), meeting demands for high precision and extreme-environment endurance.
