How to distinguish between insulating materials and anti-static materials

Electrostatic shielding material: The surface resistivity of the material is less than 1×104Ω/m2 or the volume resistivity does not exceed 1×103Ω. cm, the Faraday shield made of this material can prevent electrostatic sensitive devices from being affected by static electricity.

Electrostatic shielding materials are part of electrostatic conductor materials.

Insulating material: The surface resistivity of the material is greater than 1×1012Ω/m2, or the volume resistivity is greater than 1×1011Ω. cm. There is basically no current flow on the surface or inside of the insulating material, and its resistance is very large, making it difficult to ground. Static charges within this material remain on it for a long time.

Static conductive material: The surface resistivity of the material does not exceed 1×105Ω/m2 or the volume resistivity does not exceed 1×104Ω. Cm. This material has low resistance, and electrons flow easily on its surface and inside, and can flow to any other conductors or the ground it touches.

The surface resistivity of static dissipative materials is greater than 1×105Ω/m2 but less than or equal to 1×1012Ω/m2, or the volume resistivity is greater than 1×104Ω. cm but less than 1×10 11Ω. cm.

Antistatic generally refers to the property of a material to inhibit triboelectric charging. The antistatic properties of a material are not necessarily related to its electrical resistance or resistivity.
