A: It means the potting can withstand 18-25 kilovolts per
millimeter of thickness without breaking down, effectively
preventing electrical arcing.
Q: Is it corona resistant?
A: Yes, the silicone rubber base material offers excellent corona
resistance, suitable for high-frequency, high-voltage applications.
Q: Any special considerations for potting HV parts?
A: Absolute cleanliness is mandatory—no dust, debris, or moisture.
Potting must be uniform and bubble-free.
Q: Can it be used in EV high-voltage systems?
A: Absolutely. Its high insulation, thermal conductivity, and flame
retardancy are well-suited for automotive HV system requirements.
Q: How high is 10^16 Ω·cm volume resistivity?
