What are Conductive Compounds?

Conductive compounds offer thermally and electrically conductive paths amid components. Conductive compounds are available in two types; electrically and thermally conductive. Electrically conductive compounds offer low resistivity. They are therefore used in preventing electrostatic discharge (ESD), radiofrequency interface (RFI), and electromagnetic interface.

Conversely, thermally conductive compounds are used around heat-generating electrical devices and heat sink. These products form a thermally conductive layer within the finished product or amid components. Examples of thermally conductive layers include potting compounds, resins, and encapsulates

Normally, thermoplastics and insulators get compounded with conductive masterbatch to offer protection against electrostatic discharge. Electrostatic discharge and static discharge occur naturally. Static electricity is generated if non-conductive materials are rubbed together; one gives electrons while the other takes the electrons.

The occurrence of static electricity through friction is known as triboelectrification. Conversely, Electrostatic discharge is the sudden discharge of electrostatic charges from one body to another.

Composition of conductive compounds

Conductive compounds have filler materials added to their composition. The filler materials contain conductive masterbatch,such like carbon powder, aramid fiber, graphite powder, or chopped fiber. Other products may contain metal fillers, inorganic compounds, or glass fillers. These raw materials are starting components for finished compound production.

Material form

There are various conductive compounds material used;

Pellets or granules

These materials are formulated with resin and additives after compounding and are simply made into grain-like materials 2- 3mm in diameter. These plastic granules are then melted to be used by manufacturers of various products. There are several types of plastic granules. Those can be processed by injection, extrusion, and blow molding.

Encapsulates

Also, known conformal coatings are compounds used to cover or seal elements from environmental and mechanical ingresses. Usually, encapsulated layers are 100 MILS less in thickness.

Greases and pastes

These conductive compound materials have high viscosity to seal openings, joints, or fitting s without leakage from the gap. Vacuum sealants have a low vapor pressure, thus preventing gas leakage into the system. Greases do not polymerize or cure under normal end-use conditions. Conversely, pastes can set or cure depending on the composition.

Gap filling compounds

These compounds fill spaces or gaps between surfaces that need to be sealed or bonded. It may include compounds like form-in-place (FIP), sealants, or flexible sheet metals to seal the gaps on fluid surfaces. This will help prevent leaks and infiltration of unneeded materials.

Applications of conductive compounds

Conductive compounds are applicable in various industries. Specialized conductive compounds meet MLI specifications and are suitable for aerospace applications. Some of these compounds are used to manufacture PCBs, while others are designed for high voltage products like circuit breakers, transformers, generators, and motor assemblies.

Also, there are conductive compounds suitable for optoelectronic and automotive applications. This is because flame retardant materials reduce the spread of flames or resist ignition if exposed to high temperatures. Also, they are used by OEMs for sealing, assembly, and product fabrication.
