content: Yes, indeed it looks exactly like the one they use for transformers, and I found it using the word "polyester" thank you all!

content: Hmm, it's a little more translucent than that. Suspect it may be stretchier, too? May be a vinyl type.Also for the record, Kapton is a brand name of polyimide film.Tim

content: No, it is not that stretchy, not as much as the usually black insulating tape at least.Is that black tape vinyl?

content: Quote from: fabiodl on May 06, 2020, 03:46:50 ami doubt it. the transformer tape is alot thinner and adhesion is a bit "typical". the tape used to hold things together in consumers' product, sometime during packing is a lot thicker and adhesion is smooth and higher quality, i dont know to term it but it sticks very good but peeled off easier too than typical tape, can retain its adhesive strength with many time reapplication, do not damaging too much to a paper it stick to or such. i dont know the name either and i dont know where to source or buy them. the thickness is a bit more than kapton tape. i have both kapton and transformer tape, they are unlike those "product packing tape".

content: Hmm, could be a matte finished polyester then.Yeah transformer tape isn't so sticky, at room temperature; it's designed to flow on heating, when you varnish and bake the transformer. It's not quite as tacky at room temperature as other acrylic adhesives. Could be the same idea, but a slightly different formulation then.Tim

content: hard to tell if no experience with it. but it is spec for curing, not for products, so i dont know. i will search when i really need it, so far the normal tape can do the job.
