FKC Gap Filler is a silicone-based material formulated exclusively for the EV battery environment. This thermal interface material cures at room temperature or can be accelerated with heat and provides excellent thermal conductivity, electrical insulation, water resistance, corrosion resistance, and impact resistance properties.

1) Rapid dissipation of heat generated within the power control device for electric vehicle batteries and electric motors.

2) The gap filler inserted into electric vehicle batteries is placed between modules and packs, efficiently transferring the high heat generated in the modules to prevent the risk of fire and extend the product's lifespan

3) The gap filler, made of highly impact-resistant material, protects the product from external shocks.

Gap Filler minimizes thermal transfer interference from air or contaminants, effectively controlling heat and rapidly transferring high temperatures from heat sources. This improves the product's lifespan and protects it from external impacts with its excellent impact resistance. To effectively transfer heat generated in battery modules to the pack's thermal management system, a gap filler with high thermal conductivity is required. FKC has developed a gap filler that eliminates air bubbles during application, achieving optimal heat dissipation even in narrow spaces as small as a few hundred micrometers (µm). Additionally, it features high flowability and rapid application, maximizing production efficiency and offering excellent workability and durability optimized for automated processes. This adds value to customers by enhancing efficiency and design stability.
