Development Success: Low-Density, Highly Resilient Thermally Conductive Silicone Pads

With the rapid advancement of new energy vehicles, electric vehicles (EVs) and hybrid electric vehicles (HEVs) are becoming increasingly common. Thermal management for automotive lithium-ion batteries and electronic control units is more critical than ever, driving growing demand for high-performance thermal interface materials such as thermal conductive pads.

Meeting this need, TOUSEN—a specialized manufacturer of thermal management solutions—has introduced the TSP-Z series of thermally conductive silicone sheets, engineered specifically for EVs and HEVs. Leveraging over ten years of proprietary technology, the TSP-Z thermal pad delivers a unique combination of low density, low hardness, and high resilience, offering advanced heat dissipation for modern electric vehicles.

As electrification progresses, requirements for thermal conductive pad solutions have grown more complex. The TSP-Z series responds with an innovative lightweight design—achieving a significant density reduction—while maintaining excellent thermal performance and processability. Weight is reduced by approximately 13%, a major advantage in large-area applications such as lithium-ion battery packs.

With its lower density and reliable performance, the TSP-Z thermal conductive pad series offers an optimized, lightweight solution for electric vehicles where every gram counts.
