Virgin Expandable Polystyrene EPS Resin Plastic Granules

EPS(Expandable Poly Styrene) is a lightweight, rigid, plastic foam insulation material produced

from solid particles of polystyrene. Expansion is achieved by virtue of small amounts of pentane

gas dissolved into the polystyrene base material during production. The gas expands under the

action of heat, applied as steam, to form perfectly closed cells of EPS. These cells occupy

approximately 40 times the volume of the original polystyrene bead. The EPS beads are then

molded into appropriate forms suited to their application. Products made from foamed 

polystyrene are nearly ubiquitous, for example packing materials, insulation, and foam drink cups.
