Conductive Compounds (PE)

Normally insulators, thermoplastics can be compounded with a variety of conductive fillers to provide protection from electrostatic discharge (ESD). Static electricity and electrostatic discharge (ESD) are naturally occurring phenomena. In simple terms, static electricity is electrical energy at rest on a surface. It is generally created by the rubbing together of nonconductive materials. One material gives up electrons and becomes +ve charged; the other takes on these electrons and becomes -ve charged. This generation of Static electricity by friction is termed triboelectrification. ESD is the sudden discharge of this electrostatic potential from one body to another.

Causes & Problems

In the production of modern electronics, electrostatic discharge and its control have a profound effect on the production process of logistics. As practically all electronic components and assemblies are susceptible to ESD damage, even at relatively low voltage levels, designing a proper ESD protective environment for electronic equipment is essential. Damage that occurs when protection from ESD is insufficient will most likely, lead to malfunction or failure. ESD can damage or destroy sensitive electronic components, erase or alter magnetic media. An uncontrolled ESD event can also lead to a spark which can cause an explosion in an environment with explosive gases or dust. Fire in flammable environments.

Solutions for Static Control

The best way to prevent ESD is to reduce the generation of charges in the first place. A second method of control is to provide a ground path for the safe dissipation of accumulated charges to ground. A third method is to provide shielding or protection of devices and equipments from discharge through packing. ESD can be controlled with materials such as conductive plastics, that do not generate high level of charge, that dissipate charges before they accumulate to dangerous levels or that provide electrostatic shielding that prevents charges from reaching the sensitive product. Plastiblends conductive compounds are designed to do this cost effectively while maintaining other required performance properties of the material. Plastiblends offers electrically conductive compounds based on Polyethylene, Polypropylene & Polystyrenes with surface resistance less than 105 ohms/cm2 giving an effective static shielding. These compounds are used to produce various products for the shipping, handling and storing of ESD sensitive compounds.
