EYG-R GraphiteTIM Pyrolytic Graphite Sheets Panasonic EYG-R GraphiteTIM Pyrolytic Graphite Sheets (PGS) is comprised of low thermal resistance thermal management material in 250µm and 350µm thickness options. An ideal Thermal Interface Material (TIM) solution, Panasonic EYG-R GraphiteTIM material is designed with high-compressibility characteristics to reduce contact thermal resistance between rough surfaces. EYG-R GraphiteTIM material is easy to install with a one-to-two-step process that is more cost-effective than thermal grease. GraphiteTIM has very high compressibility compared to standard PGS, which reduces thermal resistance by following gap, warpage, and distortion of targets/substrates.
