Increasing Demand due to Expanding Electric Vehicle Industry is the Key Trend

Among the biggest challenges facing Electric Vehicles (EVs) in the industry is related to thermal control. Poor thermal management can lead to inferior product performance, a shorter lifecycle, and a severe risk of thermal runaway. Thermal management plays a critical role in increasing the efficiency of electric vehicles, including charging systems, LEDs, battery packs and enclosures, housings for Advanced Driver Assistance Systems (ADAS), and Phase Change Materials (PCM) for battery cooling. Recent developments in thermally conductive polymer materials address such problems where thermal conductivity is regarded as a key attribute.

• North America witnessed a thermal conductive polymer materials market growth from USD 56.7 million in 2021 to USD 63.0 million in 2022.

The new fast charging method for electric vehicles is built around polymeric insulated wire with good thermal performance and high ampacity. Advanced polymer materials with good thermal and electrical properties to improve the performance of EV charging cables have been produced extensively in recent times. With rising demand for EV and thermal management systems in the automotive industry, product development is expected to create multiple opportunities for the global thermal conductive polymer material and plastics market.

DRIVING FACTORS

Changing Electronics Industry Trends to Increase the Demand

Factors, such as electronic device miniaturization, thermal conductivity, space constraints, and technological advancement, in the electronic device industry have prompted material demand for thermally conductive polymers in the electrical and electronics industries. Thermal conductive polymers are challenging traditional materials, such as ceramics, metal and conventional plastics, as they provide a variety of benefits such as being lighter in weight compared to metal, having reduced component counts, being easy to mold, being resistant to scratching and abrasion, having impact strength, and costing less than metal.

Thermally conductive polymer composites, which are flexible and light in weight, are used in electronics to dissipate heat generated to the surrounding area. Using fillers with specific orientations that promote heat flow results in efficient heat dissipation. For applications where heat management is crucial, such as Light Emitting Diodes (LED), photovoltaics, and automotive electronics, thermally conducting and electrically insulating plastics are of greater interest.

Thermally conductive polymer materials are used as thermal paste in laptops, phones, and others. The rising electronics production is anticipated to escalate the market growth during the forecast period.

RESTRAINING FACTORS 

Lack of Thermal Properties and Processing Difficulties to Suffocate Demand

Plastic’s limited thermal conductivity restricts its range of use. The size of electronic components has decreased massively in recent times due to the rapid development of integration and assembly technology in the electric field, necessitating the use of insulating packaging materials with good heat dissipation.

Thermally conductive polymers are neither pure plastic nor metal. Plastic has excellent mechanical and corrosion-resistant qualities but poor thermal conductivity compared to other metals. For instance, the thermal conductivity of high-density polyethylene with maximum thermal conductivity is only 0.44 W/mK, whereas the thermal conductivity of aluminum and its alloys ranges from 88 to 251 W/mK.

Thermally conductive polymer materials possess certain processing challenges that dampen the production process. Such as

• Thermal conductive polymers are heavier due to the filler content, creating concerns while processing these products.
• Due to the substantial volume of solid, granular filler, there may be settling during transportation and storage, necessitating mixing before use.
• To provide low viscosity for processing and chemical curing for stiffness and strength, many thermally conductive polymers are created as two-component systems. The mix ratio must be tested and monitored regularly within a tight window for proper curing.

Polyamide Segment Leads the Market Due to its Lower Cost and Exceptional Thermal Conductivity

On the basis of type, the market is segmented into polyamide, polybutylene terephthalate (PBT), polycarbonate, polyphenylene sulfide, polyetherimide, and others. The polyamide segment accounted for a significant market share owing to its exceptional thermal conductivity and lower cost. The polyamide segment was followed by the polycarbonate segment, which grew at a significant rate. Polycarbonates are thermally stable up to almost 135°C and are used in applications that demand thermal stability.

Polybutylene terephthalate is one of the thermoplastic polymers with high thermal conductivity. Properties, including high strength, rigidity, resistance to thermal deformation, and high dimensional stability, characterize polycarbonates. Polyphenylene sulfide is a polymer with exceptional chemical and thermal resistance. It is highly employed in applications that need thermal stability. It is a precursor to thermal conductive polymers and materials and can be converted to semiconducting by oxidizing or using dopants.

Polyetherimide, a high-performance engineering plastic, is one of the new classes of polymers that exhibit exceptional properties such as thermo-oxidative stability, high strength-to-weight ratio, high-temperature resistance, and others. However, the demand for polyetherimide is comparatively lower owing to its high price.
