ASTM E-84 is the standard test method for assessing the surface burning characteristics of building products. A new white paper from NeoGraf Solutions, “GrafGuard® Expandable Graphite Systems Help Meet ASTM E-84 Testing Requirements” discusses how GrafGuard® expandable graphite expands into a charred intumescent foam when exposed to the heat or flame, protecting the substrate and helping to pass the ASTM E-84 requirements. Minimizing both the smoke development and flame spread maximizes the potential flame spread index classification of the material. [...]Learn More
