FAQs
What is polyimide tape used for?
Polyimide film tapes are used mainly for high-temperature masking and electrical insulation. They withstand the heat of processes such as soldering, wave soldering, and powder coating, protecting areas that should not be exposed, which makes them a standard consumable in PCB and electronics manufacturing.
What adhesive does UltraTape 2158 use?
It uses an acrylic adhesive, formulated to hold at elevated temperatures and to remove cleanly so it does not leave residue on masked areas. Acrylic adhesives are common on polyimide masking tapes because they balance heat resistance with clean removal after processing.
Is this tape suitable for cleanrooms?
Yes. UltraTape 2158 is a cleanroom-grade product manufactured for use in controlled environments where low particle and contamination levels are required. Confirm the specific cleanroom class and packaging against your facility's requirements, since those details are defined by the manufacturer's data sheet.
What widths are available?
The tape is offered in a range of widths, indicated by the numeric portion of each SKU, so you can match the tape to the area being masked. Narrow widths suit fine masking on boards and components, while wider widths cover larger surfaces during high-temperature processing.
What temperature can it withstand?
Polyimide tapes are known for high-temperature performance, which is why they are used for soldering and coating masks. For the exact temperature rating, thickness, and other specifications of the 2158 series, refer to the manufacturer's data sheet and confirm the values meet your specific process requirements before use.
