GLASSMATE®-SR Graphite

GLASSMATE®-SR graphite is an ideal insert material for thick, bead transfer applications, and an economical choice for short production runs.

  • Average particle size of less than 1 micron provides premiere material strength and resistance to damage
  • Better wear resistance than traditional materials increases time between replacements

Our graphite grades are available as semi-finished rods, blocks, plates, and fully machined parts.
