The Effect of Sterculia setigera Del. Bark Extract on the Flammability of Flexible Polyurethane Foam | Chapter 11 | Theory and Applications of Chemistry Vol. 3

Fire retardant properties of the bark extract of Sterculia setigera on flexible polyurethane foam were investigated. The foam was treated with different concentrations of the extract and its flammability characteristics were compared with that of untreated sample. The result indicated increase in Ignition Time and Percentage Char with the increase in concentration of the incorporated extract while the Flame Propagation and After-Glow Time of the treated foam decreased with increase in concentration of the extract in the foam. The result revealed that the extract can significantly reduce the flammability of flexible polyurethane foam and serve to substantiate the local use of the plant in fire prevention by Hausa tribe.

The Effect of Acacia senegal Leaf Extract on the Flammability of Flexible Polyurethane Foam | Chapter 03 | Theory and Applications of Chemistry Vol. 3

Health and environmental consequences of conventional flame retardants necessitated the incorporation of new plant based flame retardants. According to Australlian Plant Society all Acacia species can be used as fire retardants which lead to the selection of the leaves of Acacia senegal as a flame retardant on flexible polyurethane foam. GC-MS analysis revealed the presence of phosphorus and nitrogen compounds. Add on percentage ranged from 10-20%, Ignition time from 8-17 seconds, flame propagation rate ranged between 0.33-0.10 cm/s, after glow time ranged from 25-5 seconds and char formation ranged from 23-30%. The flammability characteristics of the flexible polyurethane foam was improved upon doping with the extract of the leaves of this plant.
