With the advancement of technology, Gold Finger High-Temperature Tape is becoming increasingly popular. Perhaps some people aren’t familiar with this type of tape. Let’s learn more about what Gold Finger High-Temperature Tape is.
Gold Finger High-Temperature Tape (also known as Kapton Tape or Polyimide Tape) is a high-temperature specialty tape widely used in electronics, electrical, aerospace, automotive, and other fields requiring extremely high performance, such as high-temperature resistance, insulation, and a residue-free adhesive.
Composition of Gold Finger High-Temperature Tape
- Definition: Made from polyimide film as a substrate, coated on one or both sides with high-performance silicone pressure-sensitive adhesive.
- Substrate Properties: Polyimide offers excellent heat resistance, insulation, mechanical strength, and chemical stability.
- Adhesive: Typically made from imported silicone, it offers high adhesion, high-temperature resistance, and a residue-free adhesive.
Features of polyimide tape
High Temperature Resistance | Long-term operating temperature up to 260°C, and short-term resistance **above *300°C* (e.g., 300°C/10 minutes). No debonding, deformation, or warping at high temperatures.
Electrical Insulation | High dielectric strength, suitable for insulating high-voltage and high-frequency electronic components to prevent short circuits and leakage.
No Residue | After high-temperature baking, the adhesive can be removed without leaving any residual adhesive, preventing contamination of the adhered surface. It is particularly suitable for precision electronic devices.
Chemical Stability | Resistant to acids, alkalis, solvents, and oils, suitable for complex industrial environments.
Excellent Mechanical Properties | High tensile strength and excellent flexibility allow it to adhere to flat surfaces, curved surfaces, and irregular structures.
Radiation Resistance | Maintains stable performance even in radiation environments, suitable for special applications such as aerospace and nuclear industries.
Appearance and Specifications
- Color: Commonly available in brown/golden yellow, but custom options include black, white, and coffee.
- Thickness: Common thicknesses include 50 μm, 75 μm, and 100 μm (0.05 mm to 0.1 mm).
- Width: Standard widths include 10 mm, 15 mm, 20 mm, and 25 mm, but custom options are available.
- Length: Standard rolls are 33 meters, but custom options are available.
- Base Material: Polyimide film, with some products also laminated with PET release film.
