What is Tesa 51407?
Tesa 51407 is a high-temperature resistant polyimide tape coated with a special silicone adhesive system. Known for its outstanding thermal and chemical resistance, this tape performs reliably in extreme environments such as wave soldering, powder coating, and high-heat insulation tasks. Its conformability, electrical insulation properties, and clean removability make it ideal for both industrial and electronic use.
