Impact of Cellulose Modification by Expandable Graphite …
As a result, the graphite flake generates a more significant isolative layer than many intumescents. In addition, unlike the carbon char layer formed with chemical intumescent, the graphite char formed from expandable flake retains the superior heat resistance of graphite (Zabel and Solin Citation 2013). EG is a low-density carbon …
