Thermal resistivity of jacket material
Typical values for different materials are listed below.
Values are taken from IEC 60287-2-1 Ed.2.0 with following additions or deviations:
- Value for Polypropylene (PP) is based on the minimal value of thermal conductivity (0.17 to 0.22) given in the book 'Polypropylene - The Definitive Users Guide and Databook', Plastics Design Library, 1998. whereas a range of 0.10 to 0.23 is given by professionalplastics.com
- Values for silicone rubber (SiR) are taken from shinetsusilicone-global.com
- The value for chlorosulphonated polyethylene (CSM) is taken from the data sheet of Hypalon from the chemical conpany metz.net.au
