High-temperature polyimide film tape with silicone adhesive for PCB solder masking and electronics applications. Features low static protection, flame retardant, and easy-release liner for die-cut production.
The 3M™ Linered Low Static Polyimide Film Tape 5433 is a premium high-temperature electrical tape featuring DuPont™ Kapton® polyimide film with silicone adhesive, specifically engineered for PCB solder masking and other demanding high-temperature applications. This specialized tape combines exceptional thermal stability with electrostatic discharge protection, making it ideal for electronics manufacturing and assembly processes.
The polyimide film backing does not soften at elevated temperatures, providing an excellent release surface that maintains dimensional stability and prevents costly rework. The silicone adhesive delivers superior high-temperature performance while minimizing adhesive transfer, which eliminates the need for extensive cleaning and significantly improves productivity. The unique linered design features an easy-release liner that facilitates the production of precision die-cut parts, offering manufacturers greater flexibility in their production processes.
With its low static properties that virtually eliminate circuit board degradation due to electrostatic discharge, this tape helps reduce costly board waste from component failure. The tape is flame retardant, chemical resistant, and radiation resistant, providing comprehensive protection for sensitive surfaces while reducing replacement costs. Available on both cardboard and polyethylene cores, this halogen-free tape (maximum 900ppm bromine and chlorine, maximum 1500ppm total) meets stringent industry standards for electronics manufacturing and assembly applications.
