A dielectric Strength material is a substance that is a low conductor of electricity, but an efficient supporter of an electrostatic field; the concern of Dielectric Strength is needed with Electrically Insulative Epoxies. Dielectric strength can be defined as the maximum voltage required to cause a dielectric breakdown through the product. Thus meaning, it is the allowance of the insulating strength of a material. Arboron Phenolic Laminate is used as an electrical insulation sheet in power circulation operations where dielectric strength, chemical resistance, low moisture absorption, and dimensional stability are needed.
