As consumers demand "5-minute charges for 2-hour use" in smartphones and EVs, heat management has become critical. Silicone oil and silicone rubber-based thermal interface materials (TIMs) now serve as essential "cooling regulators."

Inside smartphones, high-power charging chips and batteries generate intense heat in confined spaces. Engineers apply high-thermal-conductivity silicone grease (oil-based) or thermal pads (rubber-based) between chips/heat spreaders and batteries/frames. These act as "thermal superhighways," rapidly dissipating heat to prevent throttling. Similarly, thermally conductive silicone gels bridge EV battery cells and cooling plates, boosting heat transfer efficiency by >40%.

Suppliers like Dow and Wacker continuously refine formulations. Next-gen silicone TIMs offer higher conductivity, electrical insulation, flexibility, and durability—cementing their role as enablers of safe fast-charging ecosystems.
