Whats' the minimum bend radius for 1/8 and 3/16" polycarbonate sheet?

Bending hot or cold?

I've seen references that suggest using a sheet metal brake which is an
almost negligable radius (and I assume a cold bend)

Hot you should be able to form it at will.

I don't think lexan lends itself to hot bends, however I have made
several three panel winshields in a sheet metal brake. I bends
beautifully, however don't ever spill gasoline on it, especially if it
is stressed or it will craze and shatter almost immediately.


Or ANY hydrocarbon. Don't even think about wiping with a varsol
dampened rag. Even some waxes and polishes have a hydrocarbon solvent
base and can/will damage lexan.
