Sekisui Polymatech TIM Solutions – Advanced Thermal Management for EVs & Electronics
Sekisui Polymatech – Advanced Thermal Interface Materials for Next-Gen Electronics
In today’s electronics and automotive industries, thermal management is no longer optional—it’s mission critical. With the rise of electrification, 5G networks, data centers, and high-density power electronics, devices are running hotter, smaller, and under more demanding duty cycles than ever before. Without effective Thermal Interface Materials (TIMs), excess heat leads to reliability failures,reduced efficiency, and shorter product lifetimes.
Sekisui Polymatech addresses these challenges with a comprehensive range of advanced TIM solutions engineered for EV batteries, inverters, base stations, and high-power industrial modules.
Why It Matters Now:
With EV adoption accelerating and server densities increasing, the demand for thin, flexible TIMs that can handle surface irregularities has grown. Designers need materials that combine thermal performance with mechanical compliance.
Engineering Edge:
TIMLIGHT™ sheets deliver 1.2–5.0 W/m·K conductivity, soft compressibility, and UL94 flame retardancy, ensuring reliable contact on uneven surfaces. Their tacky and reworkable nature reduces assembly complexity while enhancing long-term stability under thermal cycling.
Why It Matters Now:
Power modules in EV inverters and telecom systems are running at higher switching frequencies and temperatures. Grease breakdown or pump-out is a major reliability concern in these applications.
Engineering Edge:
CGW™ series greases are two-part formulations that cure at room temperature, forming a stable, elastic interface with conductivities up to 6.0 W/m·K. Unlike conventional greases, they maintain adhesion and minimize voids, ensuring consistent thermal pathways under vibration, power cycling, and long-term operation.
Why It Matters Now:
Power semiconductors and next-gen automotive systems (ADAS, SiC/GaN devices) require ultra-high conductivity TIMs to manage extreme heat flux in compact footprints. Conventional pads and greases cannot achieve the required performance.
Engineering Edge:
MANION™ leverages magnetic carbon fiber alignment to achieve up to 45 W/m·K conductivity, one of the highest in the industry. Thin, robust, and stable up to 200 °C, MANION™ sheets reduce junction temperatures in power modules, base stations, and EV battery cooling systems, directly enhancing system efficiency and extending service life.
Why It Matters Now:
As EV architectures evolve, designers face complex 3D geometries in battery packs, on-board chargers, and junction boxes. Standard flat TIMs cannot reliably fill gaps in these assemblies, leading to hotspots and insulation risks.
Engineering Edge:
Sekisui’s 3D Gap Pads are moldable and reworkable, with conductivity grades from 1.4 to 6.0 W/m·K. They can be formed into custom 3D shapes that conform tightly to uneven surfaces, significantly reducing thermal contact resistance. Combined with electrical insulation (≥10 kV/mm), UL94 V-0 flame retardancy, and a −40 to +150 °C operating range, they deliver safety and reliability in harsh automotive and industrial environments.
🔑 Why Engineers Should Pay Attention
・Electrification: EV batteries, inverters, and chargers generate higher thermal loads than legacy designs.
・Miniaturization: Compact telecom and data center modules leave less space for conventional cooling methods.
・Reliability Demands: Industry standards require longer lifetimes under harsher conditions.
Sekisui Polymatech TIM solutions address these challenges by combining thermal conductivity, electrical safety, mechanical compliance, and long-term reliability in one portfolio.
