Bending thin ribbon cable

Any tips for forming a crease in the brown phenolic? type of ribbon ? Not an
exact replacement of course so right angle crese in a new place. I'm
thinking of heating with the barrel of a soldering iron, practising first on
some scrap, folding over a soft edge with a radius, perhaps1/16 inch thick
softish material. While at it, how to bend the thin white or clear ribbon,
same but lower temperature ?

I'd try to bend it in the place you wanted and make a loop then heat
it with a hair dryer on the edge of the loop and see how soft it gets.


I don't think hair drier is high enough temp.

One thing I did notice, luckily, is that the bend is always on the side
where the fine conductors are, not on ground side, so forcing the ground
side to stretch , not the conductors, compressing them if anything.

Used a 300 degree C soldering iron barrel, no damage/ melting to the
phenolic and took it in 3 stages, heat bend 1/3 way and repeated twice
until a tight radius bend giving about 1/16 inch gap. Just did freehand in
the end, no 1/16 inch wide edge. At 300 deg there was still a fair amount of
resistance to bending, hence 3 attacks.
Permanent bend and no breakage in the 0.1mm conductors
