Choice of Insulations to Meet Temperature Range and Mechanical and Environmental Requirements
Insulation | Material | Temperature Range | Features |
PVC | Polyvinyl chloride | -55°C to +105°C | General-purpose insulation Good abrasion resistance Excellent flame resistance |
XL-PVC | Cross-linked PVC | -55°C to +105°C | Better abrasion and cut-through resistance than standard PVC Improved temperature and solder iron resistance over standard PVC Used in high-density wiring |
mPPE | Modified polyphenylene ether | -40°C to +105°C | Excellent recyclability Excellent abrasion and cut-through resistance Superior dielectric properties for thinner walls than PVC—allows wires 45% smaller in diameter and 40% light in weight |
PTFE | Polytetrafluoroethylene | -55°C to +200°C | High temperature Chemically inert: excellent chemical and solvent resistance Excellent electrical properties |
XLPE | Cross-linked polyethylene | -55°C to +125°C | Higher temperature rating than PVC |
Silicone | Silicone | -40°C to +150°C | High-voltage material Excellent flexibility Excellent dielectric strength and resistance to radiation, corona, and ozone |
PDVF | Polyvinylidene fluoride | -40°C to +125°C | Widely used in wire wrap applications |
ETFE | Ethylene tetrafluoroethylene | -70°C to +150°C | Widely used in wire wrap applications |
TGGT | Teflon glass glass Teflon | +250°C | High-temperature applications Chemically inert: excellent chemical and solvent resistance Moisture resistant Withstands mechanical abuse and repeated flexing |
MG | Mica glass | +450°C | High-temperature applications, such as heat-treating furnaces, kilns, and food service equipment Excellent thermal stability |
