Thermal Properties of Cable Polymers

Custom Search
Often times in the application of electrical cables, we neglect the thermal characteristics of  the polymers used in the cable insulation. Here is a list of the temperature range each of the common electrical cable polymers can withstand while in service or operation:


Cable Insulation/Polymer  Designed Temperature Range (°C)
PVC (Standard) -20 - 80
PVC (Premium) -55 - 105
Polyethylene -60 - 80
Polypropylene -40 - 105
Cross-Linked Polyethylene -40 -130
Ethylene Propylene Rubber -60 - 150
CSPE -40-105
Ethylene Vinyl Acetate (EVA) -40 - 105
CPE -40- 105
Silicone Braidless -65 - 150
Silicone with Braid -65 – 200
Teflon -70 - 260
