This is what I use. You can get it in a few colors from Farnell.

Now I checke the datasheet, which states you need 400°C. I use 350°C and
the enamel strips nicely a bit from the end of the wire if you push it
to molten solder. To strip from the center you probably need that 400°C.




That is the problem I have. I bought some that specifies 400 deg C and
that is too much heat for what I want to do. Going that hot for long
enough to melt the insulation usually lifts the traces off a board.
