TTG149 is a molded graphite material which has a highly percentage of carbonaceous materials, providing superior energy absorption. Its porous structure of graphite fibers and granulated particles provide excellent heat resistance and dissipation, as well as outstanding thermal stability in high energy applications. This material has a close relationship between static to dynamic coefficient of friction, giving smooth engagement & quiet operation, while offering high energy capability. Good oil compatibility. TTG149 is available in 0.5mm thickness through 1.5mm thicknesses.
