How to distinguish between antistatic materials and insulating materials
Antistatic materials are materials that prevent products and articles from being damaged and damaged by static electricity. Insulation materials are non-conductive materials. So how do you distinguish between anti-static materials from a professional and scientific perspective? Let me tell you the difference between the two.
Electrostatic shielding material: The surface resistivity of the material is less than 1×10^4Ω/m^2 or the volume resistivity is not more than 1×10^3Ω/cm^3. The Faraday protective cover made of this material can prevent the electrostatic sensitive device from being affected. Static effects. Electrostatic shielding materials are part of the electrostatic conductor material.
Conductive material: The surface resistivity of the material does not exceed 1 × 10 ^ 5 Ω / m ^ 2 or the volume resistivity does not exceed 1 × 10 ^ 4 Ω / cm ^ 3 . This material has a low electrical resistance, and electrons flow very easily on its surface and inside, allowing it to flow to any other conductor or ground that is in contact.
The surface resistivity of the static dissipative material is greater than 1×10^5 Ω/m^2 but less than or equal to 1×10^12 Ω/m^2, or the volume resistivity is greater than 1×10^4 Ω/cm^3 but less than 1× 10^11 Ω/cm^3.
Insulation material: The surface resistivity of the material is greater than 1×10^12 Ω/m^2, or the volume resistivity is greater than 1×10^11 Ω/cm^3. There is substantially no current flowing on the surface or inside of the insulating material, and its resistance is large and it is difficult to ground. The static charge in this material will remain on it for a long time.
