Regarding antistatic and conductive properties
Thread Content
May I ask, are the definitions of antistatic and conductive different? For example, stainless steel is a conductive material; so does it count as an antistatic material? Some people on the Internet say it’s not the case; then doesn’t stainless steel grounding transfer the static electricity away? How could it not be an antistatic material? I hope you can offer some guidance. Thank you!
It should be related to the resistance value; different environments require different resistance values, with a general requirement of not more than 100 ohms. The resistivity of 316L stainless steel is 0.71 Ω·mm2·m-1, and in many cases this value does not meet the requirements

Generally, measured in terms of surface impedance, it is typically in the range of 106 to 1012, which indicates antistatic properties； 103 and 106 are conductive.
Having a certain degree of electrical conductivity enables antistatic properties
For conductive plastics in general, the range of surface resistance is typically classified as follows. Antistatic: 10^9~10^12 Conductivity: 10^4～10^6 EMI level:
