EYG-R Series GraphiteTIM (Compressible Type) PGS

Featuring a new, thicker PGS Graphite Sheet Thermal Interface Solution with low thermal resistance

Panasonic's EYG-R series is a thicker GraphiteTIM (Compressible Type) PGS with low thermal resistance. Available in 250 µm and 350 µm thickness options, this thermal management material is an ideal Thermal Interface Material (TIM) solution designed with high compressibility characteristics to reduce contact thermal resistance between rough surfaces.

The EYG-R Series GraphiteTIM material is easy to install with a one-to-two-step process that requires much lower labor and installation costs than thermal grease.


Panasonic GraphiteTIM is a Graphite Sheet that is dedicated for use as a Thermal Interface Material. GraphiteTIM has very high compressibility compared to standard PGS, which reduces thermal resistance by following gap, warpage and distortion of targets/substrates.

Excellent heat resistance

Excellent heat resistance and reliability of GraphiteTIM allows longer service life and higher performance of various components, such as power modules.

Cost-saving option

Panasonic’s GraphiteTIM is cost-saving, because it allows the reduction of existing Thermal Management application processes. Unlike grease, GraphiteTIM eliminates the need for the printing process, since it is a sheet-type product.

More Information: Panasonic PGS Graphite Sheet

Panasonic Semi-Sealing Material (SSM) Layer is an elastomer layer that helps to facilitate the spread of heat generated by a PC board. Because it is compressible, this SSM layer fills the voids that are inherently present in any circuit board for greater contact with the heat source(s). Pyrolytic Graphite Sheet (PGS) can be ordered in 10 μm, 17 μm, 40 μm, and 50 μm thicknesses for expanded application coverage. This option is ideal for applications where both electrical isolation and thermal management are required.
