“…12 PIR foam composed of a stable three-dimensional network structure enhances char formation and reduces smoke during burning. 13,14 More isocyanurate structure makes PIR foam more resistant to fire and thermal treatment. However, high isocyanurate content is not desirable since the PIR foam becomes fragile.…”

In this study, the combinations of phosphorous‐containing fire retardants such as triethyl phosphate, oligomeric triethyl phosphate, diethyl ethyl phosphonate, diethyl hydroxymethyl phosphonate, ammonium polyphosphate, and smoke suppressant zinc borate were used as additives in order to produce non‐toxic smoke suppressant and fire‐retardant rigid polyurethane‐polyisocyanurate (PIR) foams. Flame height and smoke density of polyurethane‐polyisocyanurate foam decreased by incorporating different combinations of combustion modifiers in PIR formulations. The smoke suppressant was zinc borate. The combination of zinc borate with triethyl phosphate, oligomeric triethyl phosphate, and diethyl hydroxymethyl phosphonate resulted in a good synergy. The cone calorimeter analysis showed that the best combinations were zinc borate (10.1%) and triethyl phosphate (13.7%), or zinc borate (10.1%), triethyl phosphate (6.9%), and oligomeric triethyl phosphate (7%) and they decreased the burning and smoke formation rate of PIR foam. These combinations may be applied to produce fire‐retardant PIR foam in the industry.

“…In addition to the methods involving in situ formation of isocyanate trimers, [1][2][3] one of the approaches is to prepare polyetherols containing groupings known for their thermal resistance, such as the same s-triazine rings that are formed in the trimerization. 4 -6 A similar effect has been achieved by introducing into polyetherol structures another nitrogen-containing heterocyclic rings (e.g., purine rings).…”
