Polyimide Double-Coated Engineering Tape

The Polyimide Double-Coated Engineering Tape is a specialized industrial label engineered for demanding high-temperature environments. Its construction features a 2 mil polyimide film facestock, which provides a robust and dimensionally stable base. This film is coated on both sides with two separate 1.7 mil layers of acrylic adhesive, creating a double-sided bonding solution. The tape is designed to serve thermal transfer printing applications, requiring a resin ribbon to achieve durable, high-contrast markings that withstand harsh processing conditions. The complete assembly, including an 80 GSM white glassine liner, ensures precise die-cutting and easy handling during application.

This tape delivers exceptional performance where standard labels fail, offering reliable service across a wide temperature range from -40°C to 300°C. The double-sided acrylic adhesion ensures secure mounting during wave soldering and other high-temperature workflows, preventing fall-off, deformation, discoloration, or wear. Its polyimide core provides electrical insulation support, with suitability validated by the selected construction and process tests. The specially treated surface offers excellent printability, resulting in high scanning recognition rates for barcodes and identifiers. Additionally, the material is anti-static, meaning it does not generate static discharge that could damage sensitive electronic components, making it a safe choice for PCB handling.

Typical applications include gold-finger protection, wave soldering processes, electronics assembly, and high-temperature masking tasks. This tape is also suitable for PCB identification and protection during reflow processes in stoves or ovens. When selecting, confirm that your specific process temperature and chemical exposure align with the stated limits, and verify any electrical insulation requirements with our team before ordering.
