In 2015, a fire in Uijeongbu City, South Korea,… killed five and injured 1-hundred 26 people.
Two years later,… 29 people died in a fire at a sports club in Chungcheongbuk-do province.
In both cases, the cause of the fire was the Styrofoam planted in the buildings' outer wall.
This experiment reveals how dangerous the material can be when exposed to fire.
A pile of Styrofoam is stacked and lit inside a three-story high building.
After seven minutes, the flame quickly climbs up the wall,… and in just twelve minutes, the outer walls are completely burned.
Researchers in South Korea have succeeded in converting highly flammable Styrofoam into a fire-retardant material.
They did it by coating the Styrofoam with a carbon nanomaterial.
Ordinary Styrofoam catches fire when exposed to an open flame.
However, this coated flame-retardant Styrofoam reduces the spread of fire by forming a protective film.
"By covering it with fire-retardant liquid and making the coated side less flammable, the Styrofoam can prevent the fire from spreading entirely."
This is the country's first nanomaterial technology developed for coating fire-retardant liquid on Styrofoam.
With this new technology, the country may begin to see fewer fire hazards in the future.
