After half a year's research, DSN can provide high-performance heat conducting synthetic graphite plates with thickness up to 200 microns.
DSN is developing thicker and better performance graphite sheets, hoping to meet the needs of different markets and customers.
Here is the brief specification of the thick graphite sheet.
