A high-temperature polyimide film tape: UltraTape 2158 is a polyimide cleanroom tape with an acrylic adhesive. Polyimide film tapes are prized for two qualities in particular: excellent high-temperature resistance and good electrical insulation. Those properties have made polyimide the standard masking and insulating tape for thermally demanding electronics processes, and this cleanroom-grade version brings that capability into controlled environments where contamination must also be kept low.
Where it is used: The tape is a natural choice for masking during high-temperature operations such as soldering, wave soldering, powder coating, and PCB manufacturing, where it protects areas that must stay free of solder, coating, or heat exposure. Its film backing holds up to the temperatures these processes reach, and it can be removed afterward without leaving the residue or damage that a lesser tape might, helping keep finished boards and parts clean.
Acrylic adhesive for clean removal: The acrylic adhesive is formulated to hold reliably at elevated temperatures and then release cleanly, which is exactly the behavior a masking tape needs: it must stay put through the heat of the process, then come away without leaving adhesive behind on the masked area. As a cleanroom-grade product, it is manufactured for use in controlled environments where low particle and contamination levels are required.
Widths and specifications: The tape is offered in a range of widths, indicated by the numeric portion of each SKU, so it can be matched to the area being masked, from fine masking on boards and components to broader coverage during processing. Because the exact temperature rating, thickness, and other detailed specifications for the 2158 series are defined by the manufacturer's data sheet, users should confirm those values against their specific process requirements before use.

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.
