3M Polyimide Film Protection Tapes | DigiKey Daily

3M offers their series of polyimide film protection tapes which are engineered to provide reliable performance under high temperatures and other harsh environmental conditions. These tapes can be used for temporary or permanent holding, and are well suited for a variety of applications including solder masking, dielectric insulation, and gold finger protection. The polyimide film in these tapes is dimensionally stable at high temperatures and will not soften at elevated temperatures, meaning the tapes allow for a clean release without leaving a sticky residue behind. The 5413 series and 5419 series use a silicon adhesive, while the 7419 series is a specially formulated acrylic adhesive which is resistant to typical solder mask temperatures for short periods of time.
