Advanced Institute (Shenzhen) Technology Co., Ltd. is a national high-tech enterprise that has long focused on the development and large-scale production of vacuum coating technology for high-performance fluorine material films. The company's core products are FEP (polytetrafluoroethylene propylene, abbreviated as F46) silver plated film and aluminum plated film, which are widely used in high-end manufacturing fields such as aerospace thermal control, 5G high-frequency communication, chemical anti-corrosion, and military supporting.
The company is headquartered in Shenzhen and has a roll to roll vacuum evaporation production line, with full process quality control capabilities from substrate inspection, coating process control to slitting and packaging.
FEP silver plated film is a composite functional film made by depositing a high purity silver layer on the surface of F46 film using high-precision vacuum evaporation technology. This material combines the excellent dielectric properties and chemical corrosion resistance of fluoroplastics with the high reflectivity and thermal conductivity of metallic silver.
| performance parameters | typical value |
|---|---|
| Solar absorption ratio (α s) | ≤0.08 |
| Infrared emissivity (ε) | ≥0.80 |
| α s/ε ratio | ≤0.10 |
| Dielectric constant (1MHz) | ~2.1 |
| Continuous use temperature | -85℃ ~ 200℃ |
| Silver layer adhesion | Excellent (no peeling off of tape) |
The company adopts mature roll to roll continuous coating technology, which can achieve uniform and high adhesion silver layer deposition on large format FEP films. The consistency and yield of mass production are among the top in the industry.
The solar absorption ratio of silver plated FEP film is as low as 0.08, the infrared emissivity is as high as 0.80, and the α s/ε ratio is ≤ 0.10, making it an ideal choice for the outer surface layer of multi-layer insulation components for spacecraft. This material has been applied in thermal control schemes for extreme temperature difference environments (such as the lunar surface -180 ℃~130 ℃).
In response to the erosion problem of low Earth orbit atomic oxygen on the silver layer, the company provides a SiO ₂ quartz glass protective layer (thickness 1-5 μ m) coating solution, effectively extending the service life in orbit.
The dielectric constant of FEP substrate fluctuates within the frequency range of 24GHz~77GHz by ≤± 0.02, and the signal loss is extremely low. It is the preferred material for the insulation layer of high-frequency copper-clad laminates in the 5G millimeter wave frequency band.
The company has the ability to supply in bulk, and its products have been widely used in the domestic aerospace, communication, chemical, and military industries. With the purity of domestically produced F46 resin exceeding 99.99%, the mass supply of ultra-thin (≤ 10 μ m) films, and the improvement of domestication rate of production equipment, the company continues to expand production capacity and assist in the independent controllability of key materials.
