Lead Foil Tape: NV5LFT

Lead Foil Tape: NV5LFT

Lead Foil Tape NV5LFT is a specialized adhesive tape designed for aerospace applications, constructed with a thin layer of lead foil and a strong adhesive backing. This tape offers exceptional radiation shielding properties, making it suitable for protecting sensitive aerospace equipment from gamma rays and other forms of radiation. NV5LFT is highly malleable and conformable, allowing it to adapt to irregular surfaces and effectively seal against radiation sources in aerospace environments. Additionally, it provides resistance to chemicals commonly encountered in aerospace settings, ensuring durability and reliability. Widely used in aerospace applications, NV5LFT is essential for shielding critical components and ensuring the safety and functionality of aerospace systems.



  1. Radiation Shielding: Lead has long been used for its ability to block radiation which allows for Lead foil tape to effectively shield against gamma rays and X-rays. This property makes it valuable in applications where radiation protection is necessary, such as in medical facilities, nuclear power plants, or aerospace.
  2. Malleability and Conformability: Lead foil is highly malleable and can conform to irregular surfaces with ease. This characteristic allows NV5LFT to be applied smoothly and securely even on curved or uneven surfaces. It ensures good contact and coverage, making it suitable for various sealing and shielding applications.
  3. Chemical Resistance: Lead foil tape typically exhibits good resistance to a wide range of chemicals and environmental factors. It can withstand exposure to moisture, acids, alkalis, and other corrosive substances. This chemical resistance ensures that NV5LFT maintains its integrity and effectiveness over time, even in harsh environments.
  4. Thermal Insulation: Lead has excellent thermal insulation properties. Lead foil tape can help prevent heat transfer, making it useful for applications where thermal insulation is required. It can be applied to pipes, ducts, and other surfaces to reduce heat loss or gain, improving energy efficiency in buildings and industrial equipment.
  5. Electrical Shielding: Lead foil tape provides effective electrical shielding against electromagnetic interference (EMI) and radio frequency interference (RFI). It can be used to wrap cables, joints, and electronic components to minimize electromagnetic emissions and prevent interference with sensitive equipment. This shielding property makes NV5LFT valuable in electronic and telecommunications applications.
