According to the Persistence Market Research report, market growth is driven by the increasing demand for efficient heat dissipation in miniaturized electronics and EVs, substitution of metals with lightweight materials, and rising adoption in LEDs, 5G, and sustainable manufacturing.
Thermal conductive polymers are engineered plastic materials improved with conductive fillers such as metal particles, carbon-based materials (graphite, carbon black), or ceramic fillers (Aluminum Nitride (AlN), Aluminum Oxide (Al?O?), Boron Nitride (BN)), to significantly improve their ability to dissipate heat while retaining the processability and inherent lightness of common polymer materials. These materials are particularly useful in mechatronics and electronics, where compact design and dense component integration necessitate efficient thermal control. Depending on the fillers used, thermal conductivity can reach values up to 10–20?W/m·K, with ceramics providing electrical insulation and metals offering both thermal and electrical conductivity.

The transition of the automotive industry toward electric vehicles (EVs) is transforming the role of polymers in automotive engineering. Thermal conductive polymers are becoming vital in EV design as there is a high demand for lightweight materials that offer effective heat dissipation. Traditional polymers, with thermal conductivities around 0.2?W/m·K, are inefficient compared to aluminum alloys (~150?W/m·K), restricting their applications in thermal management, but can be rectified by incorporating filler-loaded composites.
Over 70% of plastics used in EVs are composed of just four polymers, Polyamide (PA), Polypropylene (PP), Polyurethane (PU), and PVC, which are not inherently thermally conductive polymers but can be made so for applications in EVs and electronics by incorporating special fillers or additives. PA, with a base conductivity of ~0.2 W/m·K, can be enhanced using ceramic or carbon fillers for battery cooling and electronic housings. Thermal conductive polymers play a major role in crucial components such as battery packs, enclosures, thermal interface materials (TIMs), phase change materials, motor potting compounds, and cooling channels, often incorporating fillers such as boron nitride to improve conductivity. Poor thermal management can compromise the performance, lifespan, and safety of EVs.
Thermal conductive polymers present several processing challenges despite their importance in EVs and electronics. Achieving high thermal conductivity typically requires a high loading of conductive fillers such as boron nitride or graphite, which significantly increases melt viscosity and complicates extrusion, injection molding, and compounding processes. Uniform spreading of these fillers is essential to prevent thermal hotspots and maintain mechanical integrity but there is often poor compatibility between the polymer matrix and fillers. This often leads to high interfacial thermal resistance unless surface modification or coupling agents are employed.
Filler alignment during processing can also create anisotropic heat transfer properties, making it challenging to ensure steady thermal performance. High filler content can also reduce mechanical flexibility, leading to brittle composites that are difficult to shape into different forms. Additionally, abrasive fillers hasten tool wear, raising maintenance costs, while some fillers are sensitive to processing temperatures, limiting thermal processing options.
Thermal conductive polymers combine heat dissipation, electrical insulation, and lightweight properties, making them vital across electronics, automotive, and aerospace sectors. In electronics, they replace bulky heat sinks in compact devices, serving as housings, connectors, and insulative layers, thereby improving both performance and reliability. In the automotive and aerospace industries, thermal conductive polymers enable efficient thermal management in battery housings, LED systems, and avionics, thereby reducing weight and enabling fuel efficiency. Advances in manufacturing, such as 3D printing and nanomaterial integration (graphene, carbon nanotubes), have further improved their capabilities. At the same time, sustainability is becoming vital, with research emphasizing recyclable, biodegradable, and natural-fiber-based composites.
Hybrid carbon Thermal Interface Materials (TIMs) embed carbon nanomaterials in a polymer matrix, lowering thermal resistance at the interface. This improves heat transfer from electronic components to heat sinks, thereby upgrading both device performance and reliability. These materials are essential in addressing the increasing thermal demands in high-performance computing, telecommunications, and automotive electronics. Nanomaterials such as boron nitride nanosheets (BNNS) have high thermal conductivity, electrical insulation, and thermal stability and when incorporated into TIMs, they enhance heat dissipation. These characteristics make BNNS-based TIMs suitable for futuristic applications such as smartphones, 5G systems, and EV power modules.
By product type, the polyamide segment is expected to dominate the market, holding approximately 59% of the market share during the forecast period. Their strong intermolecular hydrogen bonding imparts excellent thermal & mechanical properties. The two most common types used in packaging are PA-6 and PA-6,6. Both offer high melting points, heat resistance, flexibility, puncture resistance, thermal aging resistance, transparency, UV stability, and are excellent barriers to oxygen and many solvents. They are widely used in EVs and automotive components such as battery housings, heat sinks, and LED cooling systems; in electronics for connectors and enclosures; and in industrial applications such as motor potting and power electronics casings. Major manufacturers include Lanxess (Durethan TC), Celanese (Zytel), NUREL (Promyde®), Witcom, SABIC, BASF, and Covestro. Bio-based polyamide foams are gaining traction as eco-friendly solutions for building insulation and electrical insulation.
The polycarbonate (PC) segment is expected to experience the fastest growth over the forecast period, due to its excellent combination of mechanical strength, dimensional stability, optical clarity, and inherent flame retardancy. While unfilled polycarbonate has low thermal conductivity (~0.2 W/m·K), advanced composite formulations with thermal conductive fillers including boron nitride, graphite, or aluminum oxide can raise its conductivity to 1-10?W/m·K, making thermal conductive PC ideal for LED lighting housings, battery casings, automotive sensors and electronic device enclosures, where flame retardancy and electrical insulation are critical. Innovations include multi-functional fillers to balance heat dissipation and 3D-printed conductive parts for customized thermal management solutions. Covestro has pioneered the use of thermal conductive (TC) polycarbonate, specifically Makrolon® TC8030, in automotive applications, integrating it into an LED fog lamp housing for a major light truck OEM.
By end-use, the electrical & electronics segment is expected to dominate the market in 2025, accounting for around 45% over the forecast period, driven by the increasing demand for efficient heat management in compact devices. Thermal conductive polymers are used extensively in components such as connectors, circuit board housings, LED lighting fixtures, power modules, and TIMs. Their electrical insulation properties and enhanced thermal conductivity make them ideal for applications where both heat dissipation and electrical isolation are critical. Innovations such as filler hybridization (boron nitride with graphene) and filler alignment techniques further improve thermal performance while maintaining electrical insulation. Key manufacturers offering thermal conductive polymer compounds for electronics include Celanese (Zytel), Lanxess (Durethan TC grades), and NUREL (Promyde).
The automotive segment is anticipated to be the fastest-growing segment within this market, especially with the rise of EVs and advanced driver-assistance systems (ADAS) that require efficient thermal management. These polymers are increasingly used in battery housings, motor housings, heat sinks, LED headlamp cooling fins, and thermal interface materials to effectively dissipate heat, while reducing the overall vehicle weight. Compared to traditional metal components, thermal conductive polymers offer significant advantages such as weight savings (over 40%), corrosion resistance, electrical insulation, and design flexibility for integrated parts, which help improve vehicle efficiency and performance. Fortron® PPS is ideal for bearing blocks and mirror brackets due to its low thermal expansion and creep resistance across a wide temperature range. Hostaform® POM delivers excellent sliding performance for mirror adjustments.
