## Description

Kapton Tape 25m x 20mm is ideal for PCB masking and protection, bonding and electrical insulation in high temperature areas. The polyimide film with silicone adhesive withstands up to 260 C continuous and 300 C short term, has excellent heat and solvent stability, minimal shrinkage after baking and removes cleanly.
Kapton tape with a width of 20mm and a length of 25 meters. This is a heat-resistant adhesive tape made from polyimide film with a silicone adhesive, designed for high-temperature applications and electrical insulation.
It withstands temperatures up to 300°C for short periods and 260°C for long periods, has very good resistance to heat and solvents, and after baking, it has minimal shrinkage and removes cleanly.
It is ideal for masking and protecting circuit boards, etching processes, fiber optic cables, automotive applications such as sensors and manifolds, electrostatic painting at high temperatures, as well as semiconductor processes.
Kapton tape is also used in 3D printers in the print head assembly, precisely because of its high temperature resistance.
Specifications:
Product type: thermal insulating adhesive tape
Material: polyimide film
Adhesive: silicone
Long-term temperature resistance: 260°C
Short-term temperature resistance: 300°C
Peel resistance: over 4.5 N
Color: Transparent Brown
Width: 20 mm
Length: 25 m
Packaging: 1 roll
Usage:
Clean and degrease the surface before application for maximum adhesion.
Apply the tape with uniform pressure, without wrinkles, especially on edges or heated areas.
Use it for masking during soldering, PCB protection, temporary insulation, and fixing in high-temperature areas.
After exposure to heat, peel off slowly for clean removal.
Avoid applying on wet or dusty surfaces, as adhesion decreases.
