Heat-resistant thermally conductive silicone (100 g) (SCH-301)
Silicone for heat dissipation suitable for use in environments up to 300°C
Prices were revised effective August 1, 2025.
This silicone improves thermal conductivity in heat-dissipating areas and withstands operating temperatures up to 300°C. Simply apply a thin layer between the CPU and heat sink to enhance thermal conductivity. It is a low-molecular-weight siloxane-reduced product (designed to prevent contact failure). Available in five variations with different container sizes. View variations by container size
The container was changed in March 2026, but the contents remain the same.
