The Dual Champions of Heat-Resistant Insulation! Thanks to Their Cutting-Edge Performance, Silicones Have Become Essential Materials in the New Energy and Electronics Sectors
2026-04-08
In today’s rapidly advancing new energy and electronics industries, a “stealth material” is stepping out of the shadows to take center stage, serving as the “stabilizing force” that ensures system safety and performance—silicone. With its core properties—including resistance to extreme temperatures, excellent insulation, and chemical stability—silicone has evolved from a traditional industrial auxiliary material into an indispensable, essential material in the new energy and electronics sectors, laying a solid foundation for industrial upgrading.
In the new energy vehicle sector, battery thermal runaway remains a major industry challenge, and silicone is the key to solving this problem. Traditional materials often fail instantly under extreme temperatures above 500°C, whereas modified silicone not only withstands the rigors of a wide temperature range from -50°C to 200°C but also achieves a thermal conductivity leap from 0.2 W/(m·K) to 4.2 W/(m·K) through “dual continuous phase structure” technology. This enables rapid dissipation of battery heat while blocking heat propagation pathways. Test data from CATL shows that battery packs using high-performance silicone structural adhesives exhibit a 23% improvement in structural integrity during collisions and a 70% reduction in the rate of thermal runaway propagation, providing passengers with valuable escape time. From thermally conductive potting compounds to phase-change thermal management materials, silicone has become the “firewall” of battery thermal management.
In the electronics sector, silicone is equally a “guardian of performance.” Photovoltaic modules must withstand long-term exposure to UV radiation and humid heat. Silicone encapsulation materials, with their aging resistance and high light transmittance, not only protect solar cells but also boost power generation efficiency by 0.18%. In 5G base stations and AI servers, silicone thermal interface materials effectively solve chip cooling challenges, ensuring stable transmission of high-frequency signals. The encapsulation and protection of flexible electronic devices are also indispensable to silicone’s high elasticity and dielectric properties. From photovoltaics to semiconductors, silicone has become a core pillar of the electronics industry’s upgrade through its triple advantages of “insulation, thermal conductivity, and protection.”
More importantly, silicone’s “design flexibility” allows it to precisely meet the demands of various applications. By adjusting molecular structures, functions such as high flame retardancy, self-cleaning, and smart responsiveness can be customized. For example, the electrolyte additive HTMS enhances the high-voltage cycling performance of lithium-ion batteries, while silicone skin for humanoid robots can simulate human tactile sensations. As the “15th Five-Year Plan” accelerates new energy development, the growth rate of silicone demand will continue to outpace the industry’s overall growth, establishing it as an irreplaceable “essential material” in the supply chain.
From replacing imports to setting industry standards, and from single-function applications to smart composites, silicones are reshaping the industrial landscape with their cutting-edge performance. Their status as an essential material in the new energy and electronics sectors is not merely a result of market selection but a natural reflection of their performance advantages and technological innovation. In the future, with new breakthroughs in smart silicones and hydrogen energy sealing materials, this “universal material” is sure to inject even greater momentum into industrial upgrading.
