Product description

tesa® 51408 is a premium 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® 51408 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 provides a high peel adhesion on various surfaces and makes the tape extremely heat-resistant, withstanding extreme temperatures of up to 260°C in continuous applications.

Application Fields

  • tesa® 51408 is recommended for high temperature masking, e.g. powder coating, galvanizing
  • The premium 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
