For some materials, surface resistance rather than surface resistivity is often used to define these terms. In this case, a simple conversion factor is applied, dividing the resistivity ranges by Thus conductive becomes less than 1 x 10E4 ohms and static dissipative becomes 1 x 10E4 to 1 x 10E11 ohms, provided that the appropriate electrodes with the correct geometric conversions are used.
Conductive plastics are also used in medical devices such as pill dispensers and aerosol devices. These plastics ensure that an aerosol device dispenses a full dose of a powder or liquid to a patient rather than having the substances adhere to the device itself.

As the name implies, it is electricity at rest. The electrical charge transfers electrons that occur when there is a rubbing, sliding, or breaking of material, generating electrostatic voltages. Talking about electrostatic discharge ESD plastics, These plastics are designed to reduce static electricity to protect electrostatic-sensitive devices or limit flammable gases or liquids.
These plastics are available in many types, anti-static and static dissipative being the two most prominent ones. Build-up static electricity can occur in an insulating material like plastic when the charge tends to stay in the restricted areas of the contact between the materials. This electrostatic voltage can later be discharged with an arc or spark when it comes in contact with a body with a significantly different electrical potential. Good examples are the human body and microcircuit.
Electrostatic discharge, a sudden flow between two electrically charged objects, can have disastrous effects. Electrical sparks even bigger bad news for environments containing flammable gases and liquids. But the most common fatalities of ESD are sensitive electronic components.
Some micro-electronic parts can be damaged or destroyed by ESD as low as 20 volts. The ESD damage to a component can result in wrong readings, periodic breakdowns, and even permanent, unrepairable damage. Static Dissipative Plastic. Why Antistatic and Static Dissipative Plastics are Important A build-up of static electricity can occur when there is sliding, rubbing, or separating of a material.
Antistatic vs. Static Dissipative Conductive thermoplastics are categorized based on their surface resistance, which measures how easily an electric charge can travel across a substance.
