Lead Foil Tape: NV8LFT

Lead Foil Tape: NV8LFT

Lead Foil Tape NV8NFT is a specialized adhesive tape widely employed in the aerospace industry for shielding against electromagnetic interference (EMI) and radiofrequency interference (RFI). Its construction comprises a thin layer of lead foil backed by a strong adhesive, ensuring effective protection against radiation in sensitive aerospace electronics. This tape is crucial in maintaining the integrity of communication systems, avionics, and other electronic equipment by preventing signal interference from external sources. NV8NFT tape’s flexibility and conformability make it suitable for intricate applications, including sealing seams and joints in aircraft structures to prevent radiation leakage. Its compliance with aerospace standards underscores its reliability and suitability for critical aerospace applications.


  1. Radiation Shielding: Lead is highly effective at blocking radiation, including gamma rays and X-rays. NF8LFT can be used to create barriers or seals in environments where radiation protection is necessary, such as in medical facilities, nuclear power plants, or research laboratories.
  2. Conformability: Lead foil tape is highly malleable and conformable, allowing it to be easily applied to irregular surfaces and complex shapes. NF8LFT can be molded and shaped to fit around pipes, corners, and other challenging areas, ensuring complete coverage and a secure seal.
  3. Chemical Resistance: Lead foil tape typically exhibits good resistance to a wide range of chemicals, including acids, alkalis, and solvents. NF8LFT can withstand exposure to corrosive substances without degrading, making it suitable for use in harsh industrial environments or chemical processing facilities.
  4. Thermal Insulation: Lead is a poor conductor of heat, making lead foil tape an effective thermal insulator. NF8LFT can be applied to surfaces to prevent heat transfer, reducing energy loss or gain and improving overall thermal efficiency. It can be used in HVAC systems, insulation applications, or to seal gaps and joints in buildings.
  5. Electromagnetic Shielding: Lead foil tape provides excellent electromagnetic shielding properties, helping to block electromagnetic interference (EMI) and radio frequency interference (RFI). NF8LFT can be used to wrap cables, electronics, and sensitive equipment to prevent interference and ensure reliable performance in electronic devices and systems.
