3M Hinge Tape

Somebody posted some time ago that he used a certain type of 3M tape for his hinges.

I tried a search for "3M Hinge Tape" and got a quadrazillion hits with "hinge" and "tape". It'll take me a year to sift through these.

Does anybody know what 3M tape that was?

Did you try the "Advanced search" (for an exact phrase)?
What you need depends on what you want to do. I think many use ordinary clear packing tape. What I find in the hardware stores is usually about 3 to 5 cm wide (inch or two). Germans seem to go for the Tesa brand. On very light planes, office-type tapes may be enough.

Blenderm

Dubro is marking it "Hinge Tape". It's just 3M Blenderm, a medical tape. Buy it at a drug store for 1/3 what it costs at a hobby shop. I used it on a Potensky Eagle and found it to be very light, very soft and flexible. It started to lift off after only one day and I used a covering iron on the lowest heat to re-seal it. After about ten flights on the Eagle, more like pattern/aerobatic than 3D, the soft tape had stretched to the point that there was a lot of slop in the control surfaces. I gave up and replaced the tape with micro-hinges. It would probably work well for a very light, 3D profile, but I felt it was just not strong enough for what I needed.

I have used a number of tapes to hinge my models, including my foamy wings. I beleive the best to be ordinary 3M clear tape. This is the stuff you can find (at least here in the states) at any office supply store. It has a rather aggressive adhesive, is very tough and does well in the sun. I have been using it exclusively for almost three years and it has never failed: It hasn't turned yellow. It hasn't 'let-go'. It hasn't cracked or gotten hard. It is not damaged by a covering iron.

I use two layers, one top & one bottom & have an application technique that ensures that the hinge line is straight and flat. Two of my planes frequently exceed 100 mph (Wedgie & eZipper) with no signs of flutter.

Darrell,

Were you using the blenderm with the little holes (to make it easier to tear) for the hinges? I havent had issues with blenderm myself on my 3D foamies and the local drug store only has the easy tear kind. Was wondering if that stuff is as good.

Thanks.

I actually bought it at LHS. It is labeled 'Dubro Hinge Tape'. Pretty expensive (I think about $5, while the Blenderm is about $1.50). The Dubro tape still has the '3M Blenderm' label on the inside of the roll . It did not have perforations for tear. Unless you require extreemly light weight, I would think regular packing/sealing tape would be better (and a lot cheaper).

Thanks. Just wanted to make sure it wasnt the same stuff. I had concerns how well the
perforated tape performed.

I did find blenderm at the local medical supply. Non-perforated is $1.95 a 5yd roll. Much better than $5 for 5 yards.

Hmm.......I use the 3M blenderm tape and it works great. I never thought I would hear anyone state this tape would lift off. The adhesive is very strong.

I use 3M clear vinyl tape called Scotch Plastic I get at the hardware or lumber store. It has catalog number 190 and is usually in a rack with tapes of many different colors.

Never had an issue with BLenderm. Another choice is 3M Extreme packing tape.

Blenderm is great. Make sure it is true blenderm. There a lot of other ones at the local drug store that look similar but are not blenderm. I could not find true blenderm at Walgreens, CVS, or Eckerds. I found 12 rolls for of 1" $25 here http://www.nyblimp.com/superior/tape.htm#blenderm
Same as Dubro is packaging. I use for all my hinging needs. I use 3M Satin Tape from Office Depot or Staples for all other needs.

Medical supply places usually sell it by the single roll.

Hello,
You may be looking for 3M transparent tape. It comes 3/4" wide on a 4" roll.
Its just like packing tape, but only 3/4" wide. Sticks great to the foam.
You can pick it up at Staples or any good office supply store.
I think it a $1.50 or so a roll.
