Choose the Right Tape in 4 Steps
Follow these steps to eliminate unsuitable options almost entirely from the first step, without needing to read every specification.
Identify the temperature and duration the tape will be exposed to, as tapes have different ratings for short-term and continuous use.
Determine if you need it to be conductive, insulating, or non-electrical. If conductive, check if the adhesive layer also needs to be conductive.
Check surface energy (PP, PE, PTFE require specific adhesives) and smoothness. Textured surfaces require thicker adhesive.
Request samples to test in actual production conditions. Check adhesion strength, removability, and adhesive residue after heat exposure.

Frequently Asked Questions
Which tape is suitable for soldering masking (wave / reflow)?
Polyimide Tape (Kapton), such as WE-PI50, withstands high temperatures and peels off cleanly without leaving adhesive residue on the board, eliminating the need for individual IPA washing.
How does "conductive" copper tape differ from regular copper tape?
It depends on the adhesive layer — conductive versions allow current to flow through the adhesive, creating a continuous ground path ideal for EMI shielding. Regular adhesive acts as an insulator, which might secure all points but still fail EMC testing.
Can I order custom widths / die-cuts, and is there a high MOQ?
Yes, we have our own slitting, die-cutting, and laminating machines to cut to your exact sizes/designs. No high MOQ is required, supporting everything from R&D to mass production.
Which tape should be used for transformer / motor applications requiring UL certification?
Polyester insulation tape, such as 3M 1350F-1, has a UL rating (130°C) and can be used as a reference during certification submission, reducing the risk of failing UL/CE certification.
Can I request samples for testing before placing a real order?
Yes, simply send us your job specifications. Our team will guide you from the first step to the recommended model, and provide samples for you to test under actual production conditions before making a decision.
Where do the specifications (temperature, UL) on this page come from, and how reliable are they?
All stated values are referenced directly from the manufacturer's Technical Data Sheet (TDS), such as 3M, and Wetape's own specification catalogs. If you need to use them for official documents, such as applying for UL/CE, we recommend requesting the latest TDS file from our team for clarity before actual use.
