A friend of mine owns an ice sculpting business and wants me to replace some low voltage (22 AWG shielded) cables with some that won't crack and break like the ones that are already factory installed on a CNC machine that is in his freezer. The machine is used to carve blocks of ice so the cables are constantly moving and bending in the same place and are always breaking. Any help would be appreciated. Thanks.
 
Different PVC formulations can have different temperature ratings, such as -55?C to 105?C or -20?C to 60?C.
FEP (Teflon) is good between -70?C and 200?C
EPDM is supposed to have good flexibility between -50?C and 150?C

Here's a list of the insulation types available with Belden instrumentation cable. The maximum temperatures are listed, but not the minimum...

XLPE/PVC 90?C
XLPE/CPE 90?C
PVC/PVC 105?C
PVC/CPE 105?C
PE/PVC 75?C
FPE/PVC 75?C
TPE/TPE 105?C
XLPE/Haloarrest 90?C
XLPE/Hypalon 90?C

I'm thinking EPDM would be a good place to start. Would Microphone Cable work for your application? Audio cable shielding is top notch, and it's designed for flexibility and durability.

Barring that, next choice for me would be something like TPE
