SEKISUI’s CGW thermal Gap-Filler
For highest demands in EV battery packs and power conversion applications
Thermal management in EV battery packs and power conversion applications is key to accommodating the ever-growing challenges in the mobility sector: from shrinking form factors and higher power density to the needs for higher performance in battery and power conversion systems.
To meet – even exceed – these demands, SEKISUI POLYMATECH supports you with high-performance thermal management solutions such as CGW® thermal Gap-Filler.

Core benefits of CGW thermal Gap-Filler
CGW® series are 2-component liquid silicone based thermal Gap-Filler. This liquid-dispense and cure-in-place solution exceeds the thermal management properties of gap pads and offers many benefits:
• A wide range of thermal conductivity levels
• Super low volatile siloxane content
• Low density and weight
• Low viscosity options for injection process
• Less abrasion to support the lifetime of dispensing equipment
• Optimized rheological properties
• Long working time and rework ability of the material
• In field proven long-term reliability
Applications of SEKISUI's CGW thermal Gap-Filler
Battery Thermal Management Adhesives
EV battery pack designs require an advanced and robust thermal management concept which assures lifetime and performance of the battery cells. The battery system’s thermal management here strongly depends on an efficient and reliable heat transfer towards cooling plates.
SEKISUI’s CGW® TCAs, the advanced thermally conductive adhesives provide both a reliable structural bond towards the battery cooling system as well as a superior thermal transfer. Combining both key characteristics it still is able to maintain a high degree of elongation to follow possible cell expansion and contraction, e.g. during fast charging or rapid discharging.
The SEKISUI's new designs CGW-2ST (2W/mK) and CGW-3ER (3W/mK) both offer a stable 2-component (1:1) TCA solution optimised for highly efficient and automated dispensing process. This provides an optimal thermal and structural connection of the battery cells to the EV-batteries cooling systems, compensating for dimensional tolerances and thermally induced stress.
They remain adaptable for customer specific design and process requirements like TIM-reworking window or fast adhesion features while still allowing a clear focus on design-to-cost aspects.
CGW® wets the surfaces evenly and without pressure, remains flexible even when cured and connects the cell structures with cooling plates. Thus, ensuring your battery's performance, range and lifetime.

Power conversion for EV, PHEV and HEV
High power density, magnetic components with uneven contours and wide mechanical tolerances are common in power conversion applications. Fast charging cycles and high reliability is regarded as a standard by customers. Therefore, engineers are looking for ways to enhance heat flow to extend product lifetime and increase power efficiently.
The solution lies within thermal management components, able to meet robust mechanical and durability properties. To meet the rising demands in the power conversion infrastructure, SEKISUI offers high-performance grades such as CGW® -3.6 and CGW® -4.5.
Curing behavior over time
The dispensable fomular of our filler material allows for easy and uniform distribution. This makes for easy handling and safe processes – especially for highly automated and large volume programs.
Approved supplier to OEM and EV applications
