Electrical rigidity*: Excellent (polyethylene 20-30 kV/mm)

*Electrical rigidity, also known as dielectric strength or breakdown voltage, represents the ability of a material to withstand a certain electric voltage before a discharge or breakdown occurs. High electrical rigidity is desirable in materials intended for electrical insulation, such as those used in cables, transformers, capacitors, and other electrical and electronic components.

Electrical rigidity is primarily classified based on the breakdown voltage, which depends on the material and its thickness.
