Thin Intumescent Sheet with Uni-Directional Expansion
* 65 NH is more expensive than the other graphite compounds with similar performance, but is a U.L. Component Recognized Material.
** Typically the graphite-based products will expand more, compact, and form a hard char as they fill an enclosed area as compared to the non-graphite-based FB-525 that will expand freely and form a hard char. Generally, the high expansion graphite-based products will also exert greater pressure than the non-graphite-based products when they are confined.
