An experimental program was conducted to study the thermochemical and flammability characteristics of an improved polyisocyanurate foam, uncoated and coated either with fluorinated copolymer or an intumescent material. Testing methods included thermal analysis; scanning electron microscopy; infrared photography; infrared spectroscopy; HLT‐15, ASTM D‐1692, Bureau of Mines Penetration, and XP‐2 smoke chamber flammability tests; limiting oxygen index (LOI); and a moderate‐scale fire simulation test. The uncoated and coated foams were found to have excellent flammability and insulation characteristics, although smoke development was substantial.
