With the rapid advancements in technologies such as microelectronics, electrical insulation, and LED lighting, the demand for high-thermal-conductivity, high-insulation polymer materials continues to grow. Insulating thermally conductive polymer-based composites are materials that can efficiently transfer heat while maintaining electrical insulation—making them indispensable in applications like thermal management systems, aerospace, and electronics engineering. These composites primarily include insulating thermally conductive plastics, insulating thermally conductive rubbers, insulating thermally conductive adhesives, and insulating thermally conductive coatings.

　　Insulating and thermally conductive plastics are innovative materials developed specifically to meet the demands of high integration and multi-layered designs in industries such as electronics and lighting, while also offering excellent electrical insulation and thermal conductivity. Currently, the primary polymer matrix materials used in these insulating and thermally conductive plastics include: nylon, liquid crystal polymers, polyether ether ketone, acrylonitrile-butadiene-styrene (ABS), polypropylene, polycarbonate, polybutylene terephthalate, and polyoxymethylene, among others.

　　Insulating and thermally conductive rubber is a composite material based on matrices such as silicone rubber and nitrile rubber, offering excellent resilience, tensile strength, a low coefficient of thermal expansion, superior dielectric properties, chemical resistance, and durability across a wide range of temperatures—from extreme heat to freezing cold. Commonly used matrices today include silicone rubber, polyurethane resin, nitrile rubber, styrene-butadiene rubber, and other thermoplastic elastomers.

　　Insulating thermally conductive adhesives are widely used in various applications, including insulation and heat conduction in multilayer boards for micro-packaging, insulation and thermal management of rectifiers and thermistors, as well as bonding in chemical heat exchangers. These adhesives can be categorized into thermally conductive adhesives and thermally conductive pastes. Thermally conductive adhesives are typically formulated using organosilane or epoxy-based matrices, combined with insulating, thermally conductive fillers to create either an adhesive or a film-like material. On the other hand, thermally conductive pastes consist of highly thermally conductive particles dispersed in silicone oil or other liquid polymer matrices, resulting in a paste-like material that maintains good fluidity or exhibits a viscous consistency. Additionally, insulating thermally conductive coatings—composed of resin-based composite thin layers—are primarily applied to electronic components such as motor windings.
