[Product Name]FEP silver plated film (perfluoroethylene propylene silver plated film)
[Product alias]FEP silver plated film, silver plated FEP film, FEP electromagnetic shielding film
[Product Definition]FEP silver plated film is a high-performance composite film made by depositing a high purity silver layer on the surface of a polytetrafluoroethylene (FEP) film using vacuum magnetron sputtering technology. FEP is a copolymer modified material of polytetrafluoroethylene (PTFE), inheriting the excellent chemical inertness, low dielectric constant, and wide temperature range stability of PTFE, while also possessing thermoplastic processing capabilities. The silver plating layer endows the film with high conductivity and high infrared reflectivity.
【 Base Material 】Perfluoroethylene propylene (FEP)
【 Coating Material 】High-purity silver
[Production Process]Vacuum magnetron sputtering/vacuum evaporation

FEP silver plated film can be thermoplastic processed and supports conventional molding methods such as injection molding, extrusion, and blow molding. Compared to PTFE silver plated film (which requires sintering and pressing and is difficult to process), this product has higher production efficiency and better molding accuracy, making it suitable for large-scale applications.Advanced Institute (Shenzhen) Technology Co., LtdWe have achieved stable mass production of ultra-thin (≤ 10 μ m) FEP silver plated films using our independently developed roll to roll magnetron sputtering process.

|---|---|---|---|---|---|
| FEP silver plating (this product) | Good (thermoplastic) | 200℃ | extremely strong | extremely low | Moderate to high |
| PTFE silver plating | Poor (sintering and pressing) | 260℃ | extremely strong | extremely low | high |
| PET silver plating | Good | 150℃ | General | higher | low |
