tesa® 51407

Standard Grade Polyimide Tape 260°C / 500°F

Product description

tesa® 51407 is a standard grade polyimide tape with a silicone adhesive that has been specially developed to provide a solution for applications which require high temperature and chemical resistance. 
tesa® 51407 is used for various applications, especially for wave soldering, thermal insulation and cable wrapping, as well as masking during powder-coating processes where the tape enables sharp color edges and offers excellent paint anchorage. The polyimide tape's silicone adhesive system makes the tape extremely heat-resistant, withstanding extreme temperatures of up to 260°C / 500°F in continuous applications. tesa® 51407 standard grade polyimide tape is also available in a liner version for die-cuts.

  • High temperature resistance (up to 260°C / 500°F)
  • High chemical resistance and dielectric strength
  • Good conformability, thin backing for sharp paint lines
  • Residue-free removability for masking applications

Main applications

  • tesa® 51407 is recommended for high temperature masking, e.g. powder coating, galvanizing
  • The standard grade polyimide tape can be used for chemical production processes and wave soldering, e.g. during circuit board assembly
  • Suitable for masking of 3D printing beds or electrical and thermal insulation, e.g. wire or cable wrapping
