Does PLEXIGLAS form burning melt or burning droplets?
Like all thermoplastics, PLEXIGLAS melts in the event of fire. But the melt flow depends very much on the development of the fire and the PLEXIGLAS grade employed. Extruded PLEXIGLAS forms a larger amount of melt, cast PLEXIGLAS virtually none. PLEXIGLAS is rated B2, normally flammable, to DIN 4102, without burning droplets.
