Can antistatic rubber pads eliminate static electricity?

How Antistatic Rubber Gaskets Work: Antistatic rubber gaskets do not directly eliminate static electricity. Instead, they create conductive paths by adding conductive materials (such as carbon black or metal particles). When static electricity is generated, these conductive paths allow the charge to be slowly released to the grounding terminal, preventing rapid charge accumulation. Their surface resistivity is typically between 10^6 and 10^9 ohms, preventing electrostatic sparks without the risk of short circuits due to excessive conductivity.

 

Applicable Scenarios and Differences in Effectiveness:

Electronic Assembly Tables: Prevent sensitive components from being damaged by electrostatic discharge; requires the use of a grounding wire.

Laboratory Workbenches: Reduce dust adsorption and maintain a clean environment.

Flammable Locations: Reduce the risk of static electricity ignition, but conductivity needs to be tested regularly.

Effectiveness is significantly affected by ambient humidity: When relative humidity is below 30%, the static control capability decreases by approximately 40%; the effect tends to stabilize when humidity is above 60%.

 

Precautions for Use

Ensure proper grounding: Ungrounded pads may become static electricity reservoirs.

Avoid covering the surface with insulating layers: Paint or plastic film will block conductive paths.

Regular cleaning and maintenance: Oil stains can increase surface resistance by 10-100 times.

Use in conjunction with other measures: In ultra-dry environments, use with a humidifier or ionizer.
