Information summary：The insulation performance of ETFE anti-corrosion coating sprayed on the head is very good, which is reflected in the following aspects: 1. High volume resistivity: At temperatures close to room temperature, ETFE has a volume resistivity of up to 1017 Ω· cm, which can meet general insulation requirements even under high temperature conditions. This means that it is difficult for current to pass t

The insulation performance of ETFE anti-corrosion coating sprayed on the head is very good, which is reflected in the following aspects:
1. High volume resistivity: At temperatures close to room temperature, ETFE has a volume resistivity of up to 1017 Ω· cm, which can meet general insulation requirements even under high temperature conditions. This means that it is difficult for current to pass through ETFE coating, which can effectively prevent the conduction of current on the surface of the head and reduce the risk of leakage.
2. High surface resistance: The surface resistance of ETFE can reach 1014 Ω, making it difficult for charges to accumulate on the surface of the head, effectively preventing static electricity generation and discharge, and avoiding safety accidents caused by static electricity, such as fires, explosions, etc.
3. High dielectric strength: ETFE has an insulation breakdown strength of not less than 12kV per 0.1mm in a 35 μ m thick film, with high electrical breakdown resistance and the ability to withstand high voltages without breakdown, ensuring the insulation performance of the head in high voltage environments and protecting equipment and personnel safety.
4. Low dielectric constant and dielectric loss: ETFE has low dielectric constant and dielectric loss tangent over a wide frequency range, which enables it to maintain good insulation performance in high-frequency electric fields, reducing electrical energy loss and signal interference.
