3M 5433 Low Static Polyimide Tape

3M™ Low Static Polyimide Film Tape 5433 is an industrial grade tape product that is used for release surfaces for parts fabricated at high temperature and masking printed circuit boards during soldering processes. This product features excellent chemical resistance and high temperature performance. Featuring a low electrostatic discharge, this tape is especially useful for applications with circuit boards.

Polyimide film does not soften at elevated temperatures, thus the film provides an excellent release surface at elevated temperatures
Dimensionally stable at high temperatures, which prevents rework, enabling high productivity
Flame retardant, chemical and radiation resistant which protects surfaces to help reduce replacement costs

Color: Amber

Liner Material: PET Film

Backing/Carrier Material: Polyimide Film

Adhesive Type: Silicone

TotalThickness: 2.7 mil
