GTS Series High Performance Graphite - MH&W Thermal Products

The GTS series graphite can be used in many applications requiring high thermal conductivity and extended temperature ranges. Graphite has excellent heat spreading qualities and is offered in a variety of thicknesses.

GTS graphite can be die-cut or laminated with adhesives or other materials.

NOTE: This material is electrically conductive.
NOTE: GTS-1000i has a plastic film on both sides providing insulation.
