وصف قصير
| ⧼wm-license-information-description⧽ |
Open-flame tests compare the flammability of untreated polyurethane foam (top) and an identical foam sample surface treated with a sandwich-like coating incorporating layered double hydroxides. By 90 seconds after ignition the untreated foam is completely consumed. The experimental flame retardant formed a protective residue that caused the size of the flames to decrease and then to extinguish.
