LSZH Thermoset Cords vs Thermoplastic Cords

Power cord insulations are broken down into two distinct types:

  • thermoplastic
  • thermoset

A thermoplastic material will melt when exposed to high heat or fire, while a thermoset material will not melt when exposed to heat. In fact, thermoset materials will resist softening and degrading. They will char under high heat or fire conditions.

The bottom line is thermoset materials inherently provide better emergency performance. They work best at the elevated temperatures and electrical overload conditions found in industrial applications. Their flame propagation resistance is substantially greater than any thermoplastic material.
