looking for a plastic that cold forms,wont shatter

[DANTAMPA]

I have a injection moulded part that is shaped like a "U".
The part is 2 inches wide,1 inch across the top,and .100 thick.
it is like a plastic clip.
I had some made out of a 6/6 nylon and it worked great in florida,but when subject to 20 degrees F.,and bent to extremes,it shattered and pieces when flying.
Im concerned about a possible eye injury.I would rather the part cold form that shatter at temps below 32 degrees to - 20 F.
Please if you have any suggestions for a plastic that wont brek,but still reacks like a composite ot nylon from 32 to 125 D F.
The mold is built for .016 shrink,Thank you,Dan

a grade of polycarbonate might be an option, from memory, PC has both a lower and higher operating service than 66..becareful about colouring pc though, loose a bit of its impact strength when adding a masterbatch etc..
