What is static electricity

 

The name means static electricity. Such charges are the result of electron migration. These are due to changes, friction or material separation. They are the main generators of electrostatic voltage. For example: plastics, glass fiber, rubber, textiles, etc. Under proper conditions, this charge can generate a voltage of 30,000 or 40,000 volts. When an insulating material is created, like plastic, the accumulated charge remains in the stagnation area.

When the plastic material and the human body are in contact with a suitable voltage, such as humans or microcircuits, these electrostatic voltages can then be released through arcs or sparks

The problem of electrostatic charge accumulation and electrostatic discharge have restricted many applications of "insulation" plastics, which are usually evaluated by the measurement of surface resistivity (SR) in ohms/sq. The lower the resistivity value, the more conductive the material.

 

The danger of electrostatic discharge:

 

Electrostatic discharge (ESD) occurs when two insulating surfaces rub against each other and then separate. Electrostatic discharge can damage or destroy sensitive electronic components, eliminate or change magnetic media, and cause explosions and fires in flammable environments. Electrostatic discharge can be controlled by materials, such as conductive thermoplastic modified materials, which do not generate a large amount of static charge and can be released before the charge accumulates to a harmful level.

 

Typical conductive additives:

Additives include carbon black powder, carbon fiber, metal fiber, metal-plated carbon fiber, and metal powder

=========================================

●Anti-static products:

Surface resistivity ranges from 109 to 1012 Ω/sq, which can effectively reduce frictional static electricity generation and prevent electrostatic discharge due to human contact.

●Electrostatic Dissipation Products (ESD):

Surface resistivity ranges from 106 to 109 Ω/sq, which can prevent electrostatic discharge due to human contact.

●Conductive products:

Surface resistivity ranges from 102 to 105 Ω/sq, which can eliminate frictional static electricity.

●EMI/RFI shielding products:

Surface resistivity ranges from 100 to 102 Ω/sq, which can absorb and reflect electromagnetic and radio frequency interference.
