EPS
EPS
EPS(Expandable
Polystyrene) is a lightweight, rigid, plastic foam insulation
materialproduced from solid particles of polystyrene. Expandsion is
achieved byvirtue of small amounts of pentane gas dissolved into the
polystyrenebase material during production.The gas expands under the
action ofheat, applied as steam, to form perfectly clesed cells of EPS.
How do we classfiy EPS Material?
