Overview
High expansion ratio graphite is expandable graphite screened for large volume increase on heating (often 200–300× or higher depending on grade). It is chosen when formulations need strong intumescence or rapid gap filling.
Confirm expansion ratio, onset temperature, carbon content, and mesh size against the process temperature profile.
