Thermally Conductive Plastics Market - Global Industry Analysis, Size 2024
Global
demand for thermally conductive plastics has been high in recent years
due to their unique properties and increasing number of applications.
Thermally conductive plastics are manufactured using basic polymers,
wherein the addition of fillers leads to conductive properties in
plastics. Fillers such as graphite or carbon and metal powder are added
to base polymers for the formation of thermally conductive plastics.
Depending on the application and type of filler, the degree of filling
in the base polymer can be customized.

On
the basis of raw material, thermally conductive plastics can be
segmented into different types such as PPS (polyphenylene sulfide), PBT
(polybutylene terephthalate), PA (polyamide), PC (polycarbonate), PEI
(polyethylenimine), PSU (polysulfone), PEEK (polyether ether ketone),
and others. On the basis of application, thermally conductive polymers
can be categorized into many types such as aerospace, automotive,
electrical & electronics, healthcare, industrial, and others.
Thermally
conductive plastics are the ideal replacement materials for
conventional metals used in different applications requiring heat
dissipation. Thermally conductive plastics offer advanced features such
as reduction in weight (40% lighter than metals), improved heat
dissipation, corrosion resistance, flame retardancy, and reduced cost.
Thermal conductivity of these plastics ranges from 20 W/mK to 25 W/mK.
Thermally conductive plastics can be used instead of aluminum sheets in
electronics gadgets where heat dissipation is required.
They
are also used for electronic applications such as LED fixtures, heat
sinks, electronic enclosures, and connectors. In the automotive
industry, thermally conductive plastics are employed in the
manufacturing of various automobile components that are exposed to heat
such as radiator end caps, fuel pumps, LED displays, fuel cells, and
under hood components. Their low weight along with high thermal
conductivity has led to increased demand for thermally conductive
plastics in the aerospace and aviation industries. Various aerospace
applications such as attenuation tubes, pulleys, sensor plates, and many
other parts are made up of thermally conductive plastics. Various
medical devices such as EMI (electromagnetic interference) housings,
and ESD (electrostatic discharge) protection use thermally conductive
plastics in the health care industry. These plastics offer
characteristics such as low weight and easy fabrication. These are also
less expensive as compared to metal parts. Various equipment and
industrial components used for heat dissipation such as coils, pumps,
motors/armatures, and transformers are manufactured using thermally
conductive plastics.
Significant
growth in the electrical & electronics industry is driving the
demand for thermally conductive plastics in North America, Europe, and
Asia Pacific. Factors such as easy customization as per end-use,
extended life, enhanced heat transfer, and design flexibility have led
to increased demand for thermally conductive plastics globally. Rising
demand for smart electronics and gadgets in developing regions of Asia
Pacific is fueling the growth of thermally conductive plastics.
Increasing concern regarding environmental issues has led to higher
demand for electric vehicles.
This
is another factor propelling the growth of the thermally conductive
plastics market. Factors hampering the growth of thermally conductive
plastics include their lower thermal conductivity vis-Ã -vis
conventionally used metals and fluctuating prices of raw materials.
Rapid rise in demand for LED products across the globe is expected to
boost the market for thermally conductive plastics in the near future.
Major players are investing significantly in R&D activities in
developing innovative products and increase the application range of
thermally conductive plastics. This is estimated to generate market
opportunities in the near future.
