The CR Polyimide Film is specially designed to withstand the damaging effects of "***", which can cause ionization and eventual breakdown of an insulation material or system when the voltage stress reaches a critical level. This film not only preserves the physical, mechanical, and other properties of polyimide film, but also offers outstanding ***-resistant properties.
