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.
