PET Metallized Film with Aluminum - 0.7 Ohms/Square

Formula: Polyester, PET, PETP
Form: Metallized Film
Material: Polyethylene terephthalate (PET)
CAS Number: 25038-59-9
Commodity: Polymers
Metallized With: Aluminum - 0.7 Ohms/Square

PET Metallized Film with Aluminum (surface resistivity of 0.7 ohms per square) is designed for applications where consistent electrical conductivity and durability are necessary. The vacuum-deposited aluminum layer ensures stable resistance, making it suitable for use in film capacitors, electromagnetic interference (EMI) shielding, and flexible printed circuit boards. With its specific resistance value, the film is effective in energy storage components, such as in thin-film solar cells, printed sensors, and smart packaging, where efficient power transmission and minimal signal interference are required. Researchers have tested this film to reduce energy loss and to maintain reliable performance in high-frequency, high-power electronic systems.
